H7651-33PR from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 | VSS | power_in | Ground reference for the regulator. Connect to system ground; the input and output decoupling capacitors return to this node. |
| 2 | VIN | power_in | Unregulated input supply, -0.3V to 8.5V absolute max. Requires a 1µF input capacitor (CIN) to VSS for stability. |
| 3 | VOUT | power_out | Regulated 3.3V output (H7651-33 variant), tolerance ±2%, up to 1A output current with typical dropout ~60mV at 100mA. Requires a 1µF tantalum or 6.8µF ceramic output capacitor (COUT) to VSS. |
