Description

The LD39150 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 are available. The

low drop voltage, low noise, and ultra low

quiescent current make it suitable for low voltage

microprocessor and memory applications. The

device is developed on a BiCMOS process which

allows low quiescent current operation

independently of output load current.

 Fixed and ADJ output voltages: 1.8 V, 2.5 V,

3.3 V, ADJ
