ADP5034 - Analog Devices

ADP5034 1200 mA Buck Regulators

The ADP5034 combines two high performance buck regulators and two low dropout (LDO) regulators. It is available in either a 24-lead 4 mm × 4 mm LFCSP or a 28-lead TSSOP package. tor requirement. The low quiescent current, low dropout voltage, and wide input voltage range of the ADP5034 LDOs extend the battery life of portable devices. The ADP5034 LDOs maint.

Features

regulators operate in PWM mode when the load is above a pre- Main input voltage range: 2.3 V to 5.5 V Two 1200 mA buck regulators and two 300 mA LDOs 24-lead, 4 mm × 4 mm LFCSP or 28-lead TSSOP package defined threshold. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM), improving the light load efficiency.
