The ADP222/ADP223/ADP224/ADP225 are dual, 300mA output, low noise, high PSRR voltage regulators.
The ADP222/ADP223/ADP224/ADP225 family are dual‑output, 300 mA LDO voltage regulators that combine high PSRR, low noise, low quiescent current and low dropout voltage. They are offered in a compact 8‑lead 2 mm × 2 mm LFCSP package and support fixed (0.8 V‑3.3 V) or adjustable (0.5 V‑5.0 V) output configurations.
Typical applications include portable and battery‑powered equipment, medical devices, point‑of‑sale terminals, automatic meter readers and wireless networking gear. The document provides typical application circuits, pin descriptions, thermal data and an ordering guide.
