ADI ADP5037ACPZ-R7

降压同步（2），线性（LDO）（2）40.8V ~ 3.8V，800mA1.7V ~ 5.5V

Overview

The ADP5037ACPZ-1-R7 combines two high performance buck regulators and two low dropout (LDO) regulators in a small, 24-lead 4 mm × 4 mm LFCSP to meet demanding performance and board spacerequirements.

Regulators in the ADP5037ACPZ-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.
