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.
