APPLICATION INFORMATION
EXTERNAL CAPACITORS
Like any low-dropout regulator, external capacitors are required to assure stability. These capacitors must be
correctly selected for proper performance.
Input Capacitor
A ceramic input capacitor of at least 10 µF is required. For general usage across all load currents and operating
conditions, a 10 µF ceramic input capacitor will provide satisfactory performance.
Output Capacitor
A ceramic capacitor with a minimum value of 10 µF is required at the output pin for loop stability. It must be
located less than 1 cm from the device and connected directly to the output and ground pin using traces which
have no other currents flowing through them. As long as the minimum of 10 µF ceramic is met, there is no
limitation on any additional capacitance.
X7R and X5R dielectric ceramic capacitors are strongly recommended, as they typically maintain a capacitance
range within ±20% of nominal over full operating ratings of temperature and voltage. Of course, they are typically
larger and more costly than Z5U/Y5U types for a given voltage and capacitance.
Z5U and Y5V dielectric ceramics are not recommended as the capacitance will drop severely with applied
voltage. A typical Z5U or Y5V capacitor can lose 60% of its rated capacitance with half of the rated voltage
applied to it. The Z5U and Y5V also exhibit a severe temperature effect, losing more than 50% of nominal
capacitance at high and low limits of the temperature range.
Application Information
REVERSE VOLTAGE
A reverse voltage condition will exist when the voltage at the output pin is higher than the voltage at the input pin.
Typically this will happen when VIN is abruptly taken low and COUT continues to hold a sufficient charge such that
the input to output voltage becomes reversed. A less common condition is when an alternate voltage source is
connected to the output.
There are two possible paths for current to flow from the output pin back to the input during a reverse voltage
condition.
While VIN is high enough to keep the control circuity alive, and the Enable pin is above the VEN(ON) threshold, the
control circuitry will attempt to regulate the output voltage. Since the input voltage is less than the programmed
output voltage, the control circuit will drive the gate of the pass element to the full on condition when the output
voltage begins to fall. In this condition, reverse current will flow from the output pin to the input pin, limited only
by the RDS(ON) of the pass element and the output to input voltage differential. Discharging an output capacitor up
to 1000 µF in this manner will not damage the device as the current will rapidly decay. However, continuous
reverse current should be avoided. When the Enable is low this condition will be prevented.
The internal PFET pass element in the LP38513-ADJ has an inherent parasitic diode. During normal operation,
the input voltage is higher than the output voltage and the parasitic diode is reverse biased. However, if the
output voltage to input voltage differential is more than 500 mV (typical) the parasitic diode becomes forward
biased and current flows from the output pin to the input pin through the diode. The current in the parasitic diode
should be limited to less than 1A continuous and 5A peak.
If used in a dual-supply system where the regulator output load is returned to a negative supply, the output pin
must be diode clamped to ground. A Schottky diode is recommended for this protective clamp.
SHORT-CIRCUIT PROTECTION
The LP38513-ADJ is short circuit protected, and in the event of a peak over-current condition the short-circuit
control loop will rapidly drive the output PMOS pass element off. Once the power pass element shuts down, the
control loop will rapidly cycle the output on and off until the average power dissipation causes the thermal
shutdown circuit to respond to servo the on/off cycling to a lower frequency. Please refer to the POWER
DISSIPATION/HEAT-SINKING section for power dissipation calculations.

SETTING THE OUTPUT VOLTAGE
The output voltage is set using the external resistive divider R1 and R2. The output voltage is given by the
formula:
VOUT = VADJ x (1 + (R1/R2)) (1)
The resistors used for R1 and R2 should be high quality, tight tolerance, and with matching temperature
coefficients. It is important to remember that, although the value of VADJ is specified, the final value of VOUT is
not. The use of low quality resistors for R1 and R2 can easily produce a VOUT value that is unacceptable.
It is recommended that the values selected for R1 and R2 are such that the parallel value is less than 1.00 kΩ.
This is to reduce the possibility of any internal parasitic capacitances on the ADJ pin from creating an
undesirable phase shift that may interfere with device stability.
( (R1 x R2) / (R1 + R2) ) ≤1.00 kΩ(2)
FEED FORWARD CAPACITOR, CFF
When using a ceramic capacitor for COUT, the typical ESR value will be too small to provide any meaningful
positive phase compensation, FZ, to offset the internal negative phase shifts in the gain loop.
FZ= 1 / (2 x πx COUT x ESR) (3)
A capacitor placed across the gain resistor R1 will provide additional phase margin to improve load transient
response of the device. This capacitor, CFF, in parallel with R1, will form a zero in the loop response given by the
formula:
FZ= 1 / (2 x πx CFF x R1) (4)
For optimum load transient response select CFF so the zero frequency, FZ, falls between 20 kHz and 40 kHz.
CFF = 1 / (2 x πx R1 x FZ) (5)
The phase lead provided by CFF diminishes as the DC gain approaches unity, or VOUT approaches VADJ. This is
because CFF also forms a pole with a frequency of:
FP= 1 / (2 x πx CFF x (R1 || R2) ) (6)
It's important to note that at higher output voltages, where R1 is much larger than R2, the pole and zero are far
apart in frequency. At lower output voltages the frequency of the pole and the zero mover closer together. The
phase lead provided from CFF diminishes quickly as the output voltage is reduced, and has no effect when VOUT
= VADJ. For this reason, relying on this compensation technique alone is adequate only for higher output
voltages.
Table 1 lists some suggested, best fit, standard ±1% resistor values for R1 and R2, and a standard ±10%
capacitor values for CFF, for a range of VOUT values. Other values of R1, R2, and CFF are available that will give
similar results.

ENABLE OPERATION
The Enable ON threshold is typically 1.2V, and the OFF threshold is typically 1.0V. To ensure reliable operation
the Enable pin voltage must rise above the maximum VEN(ON) threshold and must fall below the minimum VEN(OFF)
threshold. The Enable threshold has typically 200mV of hysteresis to improve noise immunity.
The Enable pin (EN) has no internal pull-up or pull-down to establish a default condition and, as a result, this pin
must be terminated either actively or passively.
If the Enable pin is driven from a single ended device (such as the collector of a discrete transistor) a pull-up
resistor to VIN, or a pull-down resistor to ground, will be required for proper operation. A 1 kΩto 100 kΩresistor
can be used as the pull-up or pull-down resistor to establish default condition for the EN pin. The resistor value
selected should be appropriate to swamp out any leakage in the external single ended device, as well as any
stray capacitance.
If the Enable pin is driven from a source that actively pulls high and low (such as a CMOS rail to rail comparator
output), the pull-up, or pull-down, resistor is not required.
If the application does not require the Enable function, the pin should be connected directly to the adjacent VIN
pin.
POWER DISSIPATION/HEAT-SINKING
A heat-sink may be required depending on the maximum power dissipation (PD(MAX)), maximum ambient
temperature (TA(MAX))of the application, and the thermal resistance (θJA) of the package. Under all possible
conditions, the junction temperature (TJ) must be within the range specified in the Operating Ratings. The total
power dissipation of the device is given by:
PD= ( (VIN−VOUT) x IOUT) + ((VIN) x IGND) (7)
where IGND is the operating ground current of the device (specified under Electrical Characteristics).
The maximum allowable junction temperature rise (ΔTJ) depends on the maximum expected ambient
temperature (TA(MAX)) of the application, and the maximum allowable junction temperature (TJ(MAX)):
ΔTJ= TJ(MAX) −TA(MAX) (8)
The maximum allowable value for junction to ambient Thermal Resistance, θJA, can be calculated using the
formula:
θJA =ΔTJ/ PD(MAX) (9)

LP38513-ADJ is available in the TO-263 THIN surface mount package. For a comparison of the TO-263 THIN
package to the standard TO-263 package see Application Note AN-1797 TO-263 THIN Package SNVA328. The
thermal resistance depends on amount of copper area, or heat sink, and on air flow. See Application Note AN-
1520 A Guide to Board Layout for Best Thermal Resistance for Exposed Packages SNVA183 for guidelines.
Heat-Sinking the TO-263 THIN Package
The DAP of the TO-263 THIN package is soldered to the copper plane for heat sinking. The TO-263 THIN
package has a θJA rating of 67°C/W, and a θJC rating of 2°C/W. The θJA rating of 67°C/W includes the device
DAP soldered to an area of 0.055 square inches (0.22 in x 0.25 in) of 1 ounce copper on a two sided PCB, with
no airflow. See JEDEC standard EIA/JESD51-3 for more information.
Figure 19 shows a curve for the θJA of TO-263 THIN package for different thermal via counts under the exposed
DAP, using a four layer PCB for heat sinking. The thermal vias connect the copper area directly under the
exposed DAP to the first internal copper plane only. See JEDEC standards EIA/JESD51-5 and EIA/JESD51-7 for
more information.

Figure 20 shows the thermal performance when the Thin TO-263 is mounted to a two layer PCB where the
copper area is predominately directly under the exposed DAP. .As shown in the figure, increasing the copper
area beyond 1 square inch produces very little improvement.
