ADM7172ACPZ Integrated Circuit Chip 2A Low Dropout Linear Regulator LFCSP-8 LDO Regulator

Product Description Of ADM7172ACPZ

ADM7172ACPZ 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, ADM7172ACPZ 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.
