ADM7172 datasheet


The ADM7172 is a CMOS, low dropout linear regulator (LDO) that operates from 2.3 V to 6.5 V and provides up to 2 A of output current. This high output current LDO is ideal for regulation of high performance analog and mixed-signal circuits operating from 6 V down to 1.2 V rails. Using an advanced proprietary architecture, the device provides high power supply rejection and low noise, and achieves excellent line and load transient response with just a small 4.7 µF ceramic output capacitor. Load transient response is typically 1.5 μs for a 1 mA to 1.5 A load step.


1. Accuracy over line, load, and temperature: ±1.5%

2. Quiescent current, IGND = 0.7 mA with no load

3. Low shutdown current: 0.25 μA at VIN = 5 V

4. Stable with small 4.7 μF ceramic output capacitor

Application Circuits :



1. Communications and infrastructure

2. Medical and healthcare

3. Industrial and instrumentation
