General Description

The LTC®3025 is a micropower, VLDOTM (very low dropout) linear regulator which operates from input voltages as low as 0.9V.

The device is capable of supplying 300mA of output current with a typical dropout voltage of only 45mV.

A BIAS supply is required to run the internal reference and LDO circuitry while output current comes directly from the IN supply for high efﬁciency regulation.
