LTC3025-1 - 500mA Micropower VLDO Linear Regulators

General Description

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

The device is capable of supplying 500mA of output current with a typical dropout voltage of only 85mV.

Key Features
