ADP7156 Datasheet RF Linear Regulator

Manufacturer: Analog Devices

Overview: Data Sheet ADP7156 1.2 A, Ultralow Noise, High PSRR, RF Linear.

General Description

The ADP7156 is a linear regulator that operates from 2.3 V to 5.5 V and provides up to 1.2 A of output current.

Using an advanced proprietary architecture, it provides high power supply rejection and ultralow noise, achieving excellent line and load transient response with only a 10 µF ceramic output capacitor.

There are 16 standard output voltages for the ADP7156.
