LT3045 Datasheet Ultrahigh Psrr Linear Regulator

Manufacturer: Linear Technology (now Analog Devices)

Overview: LT3045 20V, 500mA, Ultralow Noise, Ultrahigh PSRR Linear Regulator.

General Description

The LT®3045 is a high performance low dropout linear regulator featuring LTC’s ultralow noise and ultrahigh PSRR architecture for powering noise sensitive applications.

Designed as a precision current reference followed by a high performance voltage buffer, the LT3045 can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB.

The device supplies 500mA at a typical 260mV dropout voltage.
