ADP5041 Datasheet (Analog Devices)

ADP5041, Micro PMU

The ADP5041 combines one high performance buck regulator and two low dropout (LDO) regulators in a small 20-lead LFCSP to meet demanding performance and board space requirements.

The high switching frequency of the buck regulator enables use of tiny multilayer external components and minimizes board
