mA load)

■ Output current up to 50 mA

■ Logic-controlled electronic shutdown

■ Output voltages of 3.0; 3.3; 3.8; 5.0 V

■ Internal current and thermal limit

■ Supply voltage rejection: 63 dB (typ)

■ Only 1 µF for stability

SOT23-5L

■ Selection at 25 °C

■ Temperature range: -25 °C to 125 °C

■ Package available: SOT23-5L

Description

The LD2979 series are very low drop regulators

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.

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.
