ADP3300 is a high accuracy anyCAP low dropout linear regulator with features such as high accuracy, low dropout voltage, low capacitor requirement, compatibility with various types of capacitors, and low noise.
The ADP3300 is a member of the ADP330x family of precision low‑dropout linear regulators. It operates from 3.0 V to 12 V, delivers up to 50 mA load current, and achieves ±0.8 % accuracy at room temperature and ±1.4 % overall. Its patented architecture requires only a 0.47 µF output capacitor for stability, making it suitable for space‑constrained designs.
The device includes over‑temperature, current‑limit, low‑noise, and shutdown protections, and provides an error‑flag output that warns before regulation is lost. Typical applications include cellular phones, notebook computers, PCMCIA regulators, barcode scanners, and camcorders.
| Dropout Voltage (typical) | 80 mV at 50 mA |
|---|---|
| Maximum Load Current | 0.1 mA to 50 mA |
| Input Voltage Range | 3.0 V to 12 V |
The typical dropout voltage is 80 mV at a load current of 50 mA.
Only a 0.47 µF output capacitor is needed for stable operation.
It provides over‑temperature protection, current‑limit protection, low‑noise operation, and a low‑shutdown‑current mode with an error‑flag output.
