Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground (Vss) pin of the regulator, shown at bottom left of the SOT23 top view and labelled 1 in the typical application. |
| 2 | VOUT | power_out | Regulated output pin (2.5V for this part, ±2% accuracy), up to 300mA output current, with foldback current limiting and a 1.0uF ceramic output capacitor in the typical application. |
| 3 | VIN | power_in | Input supply pin, 8V typical and 10V absolute maximum, with a 1.0uF ceramic input capacitor in the typical application. |
