ADI ADP5023ACPZ-1-R7

Понижающий (Buck) синхронный (2), линейный (LDO) (1)31,2 В, 800 мА1,7 В ~ 5,5 В

Overview

The ADP5023ACPZ-1-R7 combines two high performance buck regulators and one low dropout (LDO) regulator in a small, 24-lead 4 mm × 4 mm LFCSP to meet demanding performance and board space requirements.

Regulators in the ADP5023ACPZ-1-R7 are activated though dedicated enable pins. The default output voltages can be externally set in the adjustable version or factory programmable to a wide range of preset values in the fixed voltage version.
