H7250-1M5R from Shanghai Siproin Microelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Supply voltage input; input range 3.5V to 15V, absolute maximum -0.3 to 18V. |
| 2 | GND | power_in | Ground connection. |
| 3 | CE | input | Enable pin, active at high level. |
| 4 | NC | unconnected | No connection; shown as NC on the SOT23-5 pin arrangement diagram. |
| 5 | VOUT | power_out | Regulated 5.0V output (±2%), output current typically 400mA at VIN-VOUT=1V. |
