This data sheet introduces ADP5024, a combined two high performance buck regulators and one low dropout (LDO) regulator in a small, 24-lead, 4 mm × 4 mm LFCSP to meet demanding power requirements.
The ADP5024 combines two high‑performance 3 MHz buck regulators (each 1200 mA) and a low‑dropout (LDO) regulator (300 mA) in a compact 24‑lead, 4 mm × 4 mm LFCSP. It offers ±3 % output accuracy, programmable or fixed output voltages, and both forced PWM and automatic PWM/PSM modes.
Typical applications include power for processors, ASICs, FPGAs, RF chipsets, portable instrumentation, medical devices, and other space‑constrained designs. The datasheet provides detailed specifications, pin descriptions, layout guidelines, and example schematics to aid designers in integrating the device.
