The ADP3301 is a member of the ADP330x family of precision low dropout anyCAP™* voltage regulators. The ADP3301 stands out from the conventional LDOs with a novel architec- ture, an enhanced process and a new package.
The ADP3301 is a precision low‑dropout regulator that delivers up to 100 mA with excellent line and load regulation. It features a novel anyCAP™ architecture that works with any type of output capacitor, ultralow dropout voltage, and very low noise.
Designed for portable and battery‑powered equipment, the device is used in cellular phones, notebooks, barcode scanners, and as a post‑regulator for switching supplies. It includes thermal overload protection, shutdown control, and an error‑flag output for fault detection.
| Accuracy (Line & Load) @ +25°C | ±0.8 % |
|---|---|
| Typical Dropout Voltage @ 100 mA | 100 mV |
| Low Shutdown Current | 1 pA |
| Input Voltage Range | 3 V to 12 V |
| Maximum Output Current | 100 mA |
Only a small 0.47 µF bypass capacitor on the output is needed for stability.
It includes thermal overload protection that limits the die temperature to 165 °C and reduces output current if the limit is exceeded.
