This product is a 600 mA Buck regulator with a 150 mA LDO
The ADP5022 is a micro power‑management unit that combines two high‑performance buck regulators and a low‑dropout regulator (LDO) in a 16‑ball WLCSP package. It operates from 2.4 V to 5.5 V input, provides up to 600 mA per buck channel, and features over‑current, thermal protection, soft‑start, and factory‑programmable output voltages.
Typical applications include USB devices, handheld products, and multivoltage power supplies for processors, ASICs, FPGAs, and RF chipsets. The device offers low quiescent current (24 µA for Buck1, 32 µA for Buck2) and a low LDO dropout of 150 mV at 150 mA, extending battery life in portable designs.
