The ADP220/ADP221 is a dual independent 200mA low dropout voltage regulator with high PSRR, low noise and small size.
The ADP220 and ADP221 are dual, 200 mA low‑dropout voltage regulators offering high power‑supply‑rejection (PSRR), low output noise and low quiescent current. They are supplied in a miniature 6‑ball WLCSP package and are suited for portable, battery‑powered equipment such as mobile phones, digital cameras and medical devices.
The document provides specifications, typical application circuits, pin descriptions, thermal data, recommended capacitor selections and ordering information. It also includes performance graphs for PSRR, dropout voltage, output noise and thermal behavior.
| Input voltage range | 2.5 V to 5.5 V |
|---|---|
| Maximum output current per regulator | 200 mA |
| Dropout voltage at 200 mA | 150 mV |
| PSRR at 1 kHz | 76 dB |
The regulators operate with an input voltage from 2.5 V to 5.5 V.
Each regulator can supply up to 200 mA of output current.
The dropout voltage is 150 mV when the load current is 200 mA.
It provides 76 dB of power‑supply‑rejection at 1 kHz.
