The ADP3330 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3330 operates with an input voltage range of 2.9 V to 12 V and delivers a load current of up to 200 mA. It features high accuracy, ultralow dropout voltage, ultralow shutdown current, any type of capacitor stability, current and thermal limiting, and low noise. It is suitable for applications such as cellular telephones, notebook, palmtop computers, battery powered systems, PCMCIA regulators, bar code scanners, camcorders, and cameras.
The ADP3330 is a precision low‑dropout regulator offering ±0.7 % accuracy at room temperature and ±1.4 % over line, load and temperature. It operates from 2.9 V to 12 V input and delivers up to 200 mA output while requiring only a 0.47 µF output capacitor for stability (anyCAP™). The device includes current limiting, thermal shutdown, an error flag, and a low‑noise shutdown pin.
The datasheet provides detailed specifications, pin descriptions, typical performance graphs, layout recommendations, and application circuits such as dual‑supply switching and noise‑reduction techniques. It also outlines absolute‑maximum ratings, thermal considerations, and guidelines for capacitor selection and PCB design.
| Ground Current (typical at 200 mA) | 34 µA |
|---|---|
| Shutdown Pin Input Voltage | ON = 2.0 V, OFF = 0.4 V |
| Required Output Capacitor for Stability | 0.47 µF (any type) |
Only a 0.47 µF output capacitor is required for stability, and any good‑quality capacitor type can be used.
The shutdown pin turns the device on at 2.0 V and off at 0.4 V.
The absolute maximum input supply voltage is –0.3 V to +16 V.
