ADP5040 Datasheet (Analog Devices)

ADP5040, Micro PMU

The ADP5040 combines one high performance buck regulator and two low dropout regulators (LDO) in a small 20-lead LFCSP to meet demanding performance and board space requirements.

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