Analog Devices ADP5023 Datasheet
The ADP5023 combines two high‑performance 3 MHz buck regulators and a low‑dropout (LDO) regulator in a compact 24‑lead 4 mm × 4 mm LFCSP package. It offers input voltage ranges of 2.3 V‑5.5 V for the buck converters and 1.7 V‑5.5 V for the LDO, with output voltage ranges of 0.8 V‑3.8 V (buck) and 0.8 V‑5.2 V (LDO). Features include programmable or adjustable output, forced PWM or auto PWM/PSM modes, and high PSRR.
The document provides detailed specifications, pin descriptions, typical application circuits, performance graphs, thermal data, absolute maximum ratings, ordering guide and mechanical dimensions. It serves as a reference for designers integrating the ADP5023 into portable, space‑constrained, or low‑power applications.
