LP38500/2-ADJ, LP38500A/2A-ADJ

1.5A FlexCap Low Dropout Linear Regulator for 2.7V to

5.5V Inputs

General Description

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.

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.

Simplified Compensation: Stable with any type of output

capacitor, regardless of ESR.

Precision Output: "A" grade versions available with 1.5%

ture.

Typical Application Circuit
