LTC3026-1 - 1.5A Low Input Voltage VLDO Linear Regulator

General Description

The LTC®3026-1 is a very low dropout (VLDO™) linear regulator that can operate at input voltages down to 1.14V.

The device is capable of supplying 1.5A of output current with a typical dropout voltage of only 100mV.

Output current comes directly from the input supply to maximize efficiency.

Key Features
