This datasheet details the Analog Devices ADP5023, a dual 800 mA buck regulator with one 300 mA LDO in an LFCSP package.
The ADP5023 is a power management integrated circuit (PMIC) that combines two high-performance buck regulators and one low dropout (LDO) regulator. Designed for space-constrained applications, it features a small 24-lead 4 mm × 4 mm LFCSP package. The device supports an input voltage range of 2.3 V to 5.5 V for the buck regulators and 1.7 V to 5.5 V for the LDO.
