Overview
The ADP151ACBZ-2.8-R7, produced by Analog Devices Inc., is an ultralow noise, low dropout (LDO) linear regulator. This device operates from an input voltage range of 2.2 V to 5.5 V and provides up to 200 mA of output current. It is designed for noise-sensitive analog and RF applications, achieving superior noise performance without the need for a noise bypass capacitor. The ADP151 is suitable for battery-operated portable equipment due to its low quiescent current and shutdown current consumption.
