The LP38513-ADJ Fast-Transient Response Low-  
Dropout Voltage Regulator offers the highest-  
performance in meeting AC and DC accuracy  
requirements for powering Digital Cores. The  
LP38513-ADJ uses a proprietary control loop that  
enables extremely fast response to change in line  
conditions and load demands. Output Voltage DC  
accuracy at 2.5% over line, load and full temperature  
range from -40°C to +125°C. The LP38513-ADJ is  
designed for inputs from the 2.5V, 3.3V, and 5.0V rail,  
is stable with 10 μF ceramic capacitors, and has an  
adjustable output voltage. The LP38513-ADJ  
provides excellent transient performance to meet the  
demand of high performance digital core ASICs,  
DSPs, and FPGAs found in highly-intensive  
applications such as servers, routers/switches, and  
base stations.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with  
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.  
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more  
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) The line and load regulation specification contains only the typical number. However, the limits for line and load regulation are included  
in the output voltage tolerance specification.  
(2) Line regulation is defined as the change in VADJ from the nominal value due to change in the voltage at the input.  
(3) Load regulation is defined as the change in VADJ from the nominal value due to change in the load current at the output.  
(4) Dropout voltage (VDO) is typically defined as the input to output voltage differential (VIN - VOUT) where the input voltage is low enough to  
cause the output voltage to drop 2%. For the LP38513-ADJ, the minimum operating voltage of 2.25V is the limiting factor when the  
programed output voltage is less than typically 1.80V.  
(5) Device operation must be evaluated, and derated as needed, based on ambient temperature (TA), power dissipation (PD), maximum  
allowable operating junction temperature (TJ(MAX)), and package thermal resistance (θJA). The typical θJA rating given is worst case  
based on minimum land area on two-layer PCB (EIA/JESD51-3). See POWER DISSIPATION/HEAT-SINKING for details.

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 k.  
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 π x 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 π x 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 π x 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 π x 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 kto 100 kresistor  
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 = ( (VINVOUT) 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)

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 19. θJA vs Thermal Via Count for the TO-263 THIN Package on 4–Layer PCB  
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.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance  
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may  
reference these types of products as "Pb-Free".  
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.  
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based  
flame retardants must also meet the <=1000ppm threshold requirement.  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.  
(6)  
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two  
lines if the finish value exceeds the maximum column width.
