TCR15AG series
1.5 A CMOS Ultra Low Dropout, Ultra High ripple rejection ratio Regulator
The TCR15AG series are CMOS single output voltage regulators with an
on/off control input, featuring Ultra low dropout voltage, low inrush current
and fast load tr ansient response.
These voltage regulators are available in fixed output voltage type from
0.65 V to 3.6 V and a djusta ble output voltage t ype from 0. 60 V to 3.6 V an d
capable of driving up to 1.5 A.
Other features include Overcurrent protection, Thermal shutdown, Inrush
current reduc tion, Under v ol tage lockout and Auto-discharge.
The TCR15AG series are offered in the ultra-small package WCSP6F (0.8
mm x 1.2 mm (typ.), t: 0.33 mm (max))
As small ceramic input and output capacitors can be used with
the TCR15AG series, these device are ideal for portable applications
that require hig h-density board assembly su c h as cellular phones.

Absolute Maximum Ratings (Ta = 25°C)
Note: Using continuously under heavy loads (e.g. the application of high temper ature/current/voltage an d the significant
change in temper ature, etc.) may cause this product to decreas e in the reliability signifi c antly even if t he operating
conditions (i. e. operating temperatur e/current/voltage, etc .) are within t he absolute maximum ratings and the
operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling

The figure abo v e shows the recommended conf i guration for us i ng a Low-Dropout regulator. Insert a capacitor at VIN ,
VOUT and VBIAS pins for stable input/output operation. (Ceramic capacitors can be used).
Connect a capac itor with a capacita nce valu e as much as 4.7µF or mor e bet ween VIN and GND pi n and 1.0 µF or more
between VBIAS and GND, and as close as possible to the pins. But simple usage of large input capacitance is known to
form unwanted LC resona nce in com binati on wit h input wire ind uctanc e. So pleas e check paramet er with the act ual devi ce
and circuit.
CFB is optional capacitance that improve Transient response, Output noise, Oscillation resistance, PSRR and
Overshoot. However, i t does not necessarily need.
VADJ is the output voltage control pin. Typical VADJ value is 0.6 V. For best performance R1 and R2 should have
similar temp erature coefficients, otherwise output voltage accuracy will be compromi sed.

2. Power Dissipation
Board-mounte d power dissipation ratings for TCR15AG series are available in t he Absolute Maximum Ratings table.
Power dissip ation is measured on the board condition shown below.
[The Board Condition]
Board material: Glass epoxy (FR4)
Board dimension: 40 mm x 40 mm (4layer)t=1.8 mm
Metal pattern ratio: approximately 70% each layer
Please allow sufficient margin when designing a board pattern to fit the expected power dissipation. Also take into consideration
the ambient tem peratur e, input voltage, out put curr ent etc. and applyi ng the ap propr iate der ating f or allo wable po wer dissi patio n

Attention in Use
Capacitors(Output, I nput, and Bias Ca pac i tor)
Ceramic capacitors can be used for these devices. However, because of the type of the capacitors, there might be
unexpected thermal features. Please consider application condition for selecting capacitors. And Toshiba recommend the
ESR of ceramic c apacitor is under 1. 0 Ω. For stable operat ion, pleas e use over 4.7 μF Input capacitor, 1.0 μF Bias capacitor
and 4.7 μF output ceram i c capacitor.
Mounting
The long distance between IC and each capacitor might affect phase assurance by impedance in wire and inductor. For
stable power supply, output capacitor need to mount near IC as much as possible. Also VIN and GND pattern need to be
large and make t he wire impedance small as possible.
Permissible Loss
Please have enough design patterns for expected maximum permissible loss. And under consideration of surrounding
temperature, input voltage, and outp ut cur rent etc, we recomm end prop er dissip ation r atings for ma ximum per miss ible loss;
in general ma ximum dissipat i on rating is 70 t o 80 percent.
Overcurrent Protection and Thermal s hutdown
Overcurrent protection and Thermal shutdown are designed in these products, but these are not designed to constantly
ensure the sup pression of the device within oper ation lim its . Depending on t he condition dur ing actua l usage, it could affect
the electrical characteristic specification and reliability. Also note that if output pins and GND pins are not completely shorted
out, these pro ducts might be break down.
When using these products, please read through and understand the concept of dissipation for absolute maximum ratings
from the above mention or our ‘Semiconductor Reliability Handbook’. Then use these products under absolute maximum
ratings in any condition. Furthermore, Toshiba recomm end inserting failsafe system into the design.
Adjustable output voltag e type
TCR15AGADJ is adjustable output voltage type. VADJ is the output voltage control pin, please refer to recommended
application circuit and ref erence resistance t able. Please select t he tolerance of the resistance value in accordance by the
system. In addition, pleas e assemble R1 an d R2 to minimiz e common impedance. For VADJ assembly,
please desig n PCB pattern as short as possible to avoid noise effect.
