ADP5043 Datasheet (Analog Devices)

ADP5043, Micro PMU

The ADP5043 combines one high performance buck regulator and one low dropout (LDO) regulator 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
