ADP5022ACBZ-1-R7 Description

ADP5022ACBZ-1-R7 is a type of micro power management unit (micro PMU) that incorporates two high-performance buck regulators and a low dropout regulator (LDO). Tiny multilayer external components and minimal board space can be achieved through buck regulators with high switching frequency. The LDO maintains power supply rejection greater than 60 dB for frequencies as high as 10 kHz while operating with a low headroom voltage. The battery life of portable devices can be extended due to its low quiescent current, low dropout voltage, and wide input voltage range. The ADP5022ACBZ-1-R7 micro PMU is available in a tiny 16-ball 2.08 mm × 2.08 mm WLCSP to save board space.
