FEATURES  
DESCRIPTION  
2
•
FlexCap: Stable with Ceramic, Tantalum, or  
Aluminum Capacitors  
TI's FlexCap LDO's feature unique compensation that  
allows the use of any type of output capacitor with no  
limits on minimum or maximum ESR. The LP38501/3  
series of low-dropout linear regulators operates from  
a +2.7V to +5.5V input supply. These ultra low  
dropout linear regulators respond very quickly to step  
changes in load, which makes them suitable for low  
voltage microprocessor applications. Developed on a  
CMOS process, (utilizing a PMOS pass transistor),  
the LP38501/3 has low quiescent current that  
changes little with load current.  
•
•
•
•
•
•
•
•
•
Stable with 10 µF Input/Output Capacitor  
Adjustable Output Voltage from 0.6V to 5V  
Low Ground Pin Current  
25 nA Quiescent Current in Shutdown Mode  
Output Current of 3A  
Available in TO-263, PFM THIN Packages  
VADJ Accuracy of ±1.5% at 25°C (A Grade)  
VADJ Accuracy of ±3.5% at 25°C (STD)  
Ground Pin Current: Typically 2 mA at 3A load  
current.  
Over-Temperature and Over-Current  
Protection  
Disable Mode: Typically 25 nA quiescent current  
when the Enable pin is pulled low.  
•
•
−40°C to +125°C Operating TJ Range  
Enable Pin (LP38501)  
Simplified Compensation: Stable with any type of  
output capacitor, regardless of ESR.  
APPLICATIONS  
Precision Output: "A" grade versions available with  
1.5% VADJ tolerance (25°C) and 3% over line, load  
and temperature.
