H7550-1 from Shanghai Siproin Microelectronics, in a SOT-23. 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 / common return for the regulator. Single-point ground connection recommended per application circuits. |
| 2 | VIN | power_in | Unregulated input supply, 6V (Vout+2V) up to 15V typical (18V absolute max). Bypass with 10µF to GND close to the pin. Pin 2 is the metal tab on SOT-89. |
| 3 | VOUT | power_out | Regulated 5.0V output, up to 150mA. Load regulation ~60mV typ (1-50mA). Requires 10µF output capacitor to GND for stability. |
