The ADP5024 is a high performance dual buck regulator and single low dropout (LDO) regulator in a small, 24-lead, 4 mm × 4 mm LFCSP package that meets demanding performance requirements.
The ADP5024 combines two high‑performance 3 MHz buck regulators and a low‑dropout regulator in a compact 24‑lead LFCSP package. It offers programmable or fixed output voltages, low quiescent current, and high PSRR, making it suitable for space‑constrained portable devices and processor power supplies.
