Description

The LD39080 is a fast, ultra low drop linear

regulator which operates from 2.5 V to 6 V input

supply.

A wide range of output options is available. The

low drop voltage, low noise, and ultra low

quiescent current make it suitable for low voltage

microprocessors and memory applications. The

device is developed on the BiCMOS process

which allows the low quiescent current operation

regardless of the output load current.
