LD2979

Very low drop voltage regulators with inhibit

Datasheet

production data

Description

The LD2979 is a very low drop regulator available

in SOT23-5L.

The very low drop-voltage and the very low

quiescent current make them particularly suitable

for low noise, low power applications and in

battery powered systems.

SOT23-5L

Features

•

Very low dropout voltage (0.2 V typ. at 50 mA

load)

•

Very low quiescent current (typ. 500 µA at 50

mA load)

•

Output current up to 50 mA

•

Logic-controlled electronic shutdown

•

Output voltages of 3.0 and 3.3 V

•

Internal current and thermal limit

•

Supply voltage rejection: 63 dB (typ)

•

Only 1 µF for stability

•

Temperature range: -25 °C to 125 °C

•

Package available: SOT23-5L

Shutdown logic control function is available on

five pin version (TTL compatible). This means that

when the device is used as local regulator, it is

possible to put a part of the board in standby,

decreasing the total power consumption.
