H7250-1 from Shanghai Siproin Microelectronics, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground / Vss reference for the regulator. Connect to the system ground plane; the input and output bypass capacitor grounds should return here. |
| 2 | VOUT | power_out | Regulated 5.0 V output (Vout × 0.98 to Vout × 1.02, ±2% accuracy). Sources up to 400 mA typical. Requires a 1 µF tantalum or 6.8 µF ceramic output capacitor to GND for stability. |
| 3 | VIN | power_in | Unregulated input supply, 3.5 V to 15 V (18 V absolute max). Bypass to GND with a 1 µF ceramic/tantalum capacitor placed close to the pin. |
