LP38500/2-ADJ, LP38500A/2A-ADJ  
1.5A FlexCap Low Dropout Linear Regulator for 2.7V to  
5.5V Inputs  
General Description  
Features  
National'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 LP38500/2 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  
LP38500/2 has low quiescent current that changes little with  
load current.  
FlexCap: Stable with ceramic, tantalum, or aluminum  
capacitors  
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  
Guaranteed output current of 1.5A  
Available in TO-263, TO-263 THIN, and LLP-8 packages  
Guaranteed VADJ accuracy of ±1.5% @ 25°C (A Grade)  
Ground Pin Current: Typically 2 mA at 1.5A load current.  
Disable Mode: Typically 25 nA quiescent current when the  
Enable pin is pulled low.  
Guaranteed accuracy of ±3.5% @ 25°C (STD)  
Over-Temperature and Over-Current protection  
−40°C to +125°C operating TJ range  
Simplified Compensation: Stable with any type of output  
capacitor, regardless of ESR.  
Enable pin (LP38502)  
Precision Output: "A" grade versions available with 1.5%  
VADJ tolerance (25°C) and 3% over line, load and tempera-  
ture.  
Applications  
ASIC Power Supplies In:  
Printers, Graphics Cards, DVD Players  
Set Top Boxes, Copiers, Routers  
DSP and FPGA Power Supplies  
SMPS Regulator  
Conversion from 3.3V or 5V Rail  
Typical Application Circuit
