●Power Dissipation
◎HTSOP-J8
Thermal design should ensure operation within the following conditions. Note that the temperatures listed are the allowed
temperature limits and thermal design should allow sufficient margin beyond these limits.
1. Ambient temperature Ta can be no higher than 85℃.
2. Chip junction temperature (Tj) can be no higher than 150℃.
Chip junction temperature can be determined as follows:
Most of the heat loss that occurs in the BDxxGC0WEFJ series is generated from the output Pch FET. Power loss is
determined by the total VCC-VO voltage and output current. Be sure to con firm the system input and output voltage and
the output current conditions in relation to the heat dissipation characteristics of the V CC and VO in the de sign. Bearing in
mind that heat dissipation may vary substantially depending on the substrate employed (due to the power package
incorporated in the
BDxxGC0WEFJ make certain to factor conditions such as substrate size into the thermal design.
Power consumption [W] = Input voltage (VCC) - Output voltage (VO) ×IO(Ave)
Example) Where VCC=5.0V, VO=3.3V, IO(Ave) = 0.1A,
Power consumption [W] = 5.0 V - 3.3V ×0.1A
=0.17[W]

●Input-to-Output Capacitor
It is recommended that a capacitor (over 1uF) is placed near pins bet ween the input pin and GND as well as the output pin
and GND. A capacitor, between input pi n an d GND, is vali d when t he p o wer supply impe dance is high or trace is long. Also,
as for the capacitor between the output pin and GND, the greater the capacitance, the more sustainable the line regulation
will be and the capacitor will make improvements of characteristics depending on the load. However, please check the
actual functionality of this part by mounting it on a board for the actual application. Ceramic capacitors usually have different,
thermal and equivalent series resistance char acteristics, and moreover capacitance decreases gradua lly in use.
For additional details, please check with the manufacturer, and select the best ceramic capacitor for your applicati on.
●Equivalent Series Resistance ESR (ceramic capacitor etc.)
To prevent oscillations, please attach a capacitor between
VO and GND. Capacitors usually have ESR (Equivalent
Series Resistance). Operation will be stable in the ESR-IO
range shown to the right. Ceramic, tantalum and
electrolytic Capacitors have different ESR values, so
please ensure that you are using a capacitor that operates
in the stable operating region shown on the right. Finally,
please evaluate in the actual application.

●Evaluation Boa r d Circuit
●Evaluation Board Parts List
●Board Layout
PCB layout considerations:
・Input capacitor CIN connected to VCC (Vin) should be placed as close to VCC(VIN) pin as possible.
Output capacitor COUT also should be placed as close to IC pin as possible. In case the part is connected to inner layer
GND plane, please use sever al throu gh holes.
・FB pin has comparatively high impedance and can be affected by noise, so stray capacitance should be as small as
possible. Please take care of this during layout.
・Please make GND pattern wide enough to handle thermal dissipation.
・For output voltage setting (BD00GC0WEFJ)
Output voltage can be set by FB pin voltage（0.800V typ.）and external resistance R1, R2.
（The use of resistors with R1+R2=1k to 90k is recommen ded）

●Operational Notes
(1) Absolute maximum ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc.,
can break down the device, t hus making it impossible to ident ify the damage mode, suc h as a short circuit or an open
circuit. If there is any possibility of exposure over the rated values, please consider adding circuit protection devices
such as fuses.
(2) Connecting the power supply connector backward
Connecting of the power supply in reverse polarity can damage the IC. Take precautions when connecting the power
supply lines. An external direction diode can be added.
(3) Power supply lines
Design the PCB layout pattern to provide low impedance GND and supply lines. To obtain a low noise ground and
supply line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power
supply terminals to ICs, connect a capacitor between the power supply and GND terminal. When using electrolytic
capacitors in a circuit, note that capacitance values are reduced at low temperatures and over time.
(4) GND voltage
The potential of the GND pin must be minim um potential under all operating conditions.
(5) Thermal design
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating
conditions.
(6). Inter-pin shorts and mounting errors
Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any
connection error or if pins are shorted togeth er.
(7). Actions in strong electromagnetic field
Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to
malfunction.
(8). ASO
When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO.
(9). Thermal shutdown circuit
The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is
designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or guarantee its
operation. Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation
of this circuit is assumed.
(10). Testing on application boards
When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to
stress. Always discharge capacitors after each process or step. Always turn the IC’s power supply off before connecting
it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an
antistatic measure. Use similar precaution when transporting or storing the IC.

(11). Regarding input pin of the IC
This monolithic IC contain s P+ isolation and P substrate la yers between adjacent element s in o rder to keep them isolated.
P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a
parasitic diode or transistor. For example, the relation between each potential is as follows:
When GND > Pin A and GND > Pin B, the P-N j unction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes can occur inevitable in the structure of the IC.
The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical
damage. Accordingly, methods by which parasitic diodes operate, such as applyi ng a voltage that is lower than the
GND (P substrate) voltage to an input pin, should not be used.
(12). Ground Wiring Pattern.
When using both small signal and lar ge current GND patterns, it is recommended to isolat e the two ground patterns,
placing a single ground p oint at the ground potential of applicati on so that the pattern wiring resistance and voltage
variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to
change the GND wiring pattern of any external components, either.

Precaution on using ROHM Products
1. Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment,
OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you
intend to use our Products in devices requiring extremely high reliability (such as medical equipment (Note 1), transport
equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car
accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or
serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance.
Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any
damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific
Applications.

2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3. Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning
residue after soldering
[h] Use of the Products in places subject to dew condensation
4. The Products are not subject to radiation-proof design.
5. Please verify and confirm characteristics of the final or mounted products in using the Products.
6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8. Confirm that operation temperature is within the specified range described in the product specification.
9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
Precaution for Mounting / Circuit board design
1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product
performance and reliability.
2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the
ROHM representative in advance.
For details, please refer to ROHM Mounting specification
