LT1528 - 3A Low Dropout Regulator

Datasheet Summary

Description

The LT ®1528 is a 3A low dropout regulator optimized to handle the large load current transients associated with the current generation of microprocessors.

This device has the fastest transient response of currently available PNP regulators and is very tolerant of variations in capacitor ESR.

Features

  • n Dropout Voltage: 0.6V at IOUT = 3A n Fast Transient Response n Output Current: 3A n Quiescent Current: 400μA n No Protection Diodes Needed n Fixed Output Voltage: 3.3V n Controlled Quiescent Current in Dropout n Shutdown IQ = 125μA n Stable with 3.3μF Output Capacitor n Reverse Battery Protection n No Reverse Output Current n Thermal Limiting.
