HG8805M5 from HGSEMI, 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 | Regulator input supply; absolute maximum 8 V, with line regulation specified for Vin up to 6.5 V. |
| 2 | Gnd | power_in | Ground pin; ground pin current is 50 µA typ and 85 µA max for Iout from 0 to 600 mA. |
| 3 | EN | input | Enable/shutdown input; threshold low is 0.4 V max and high is 2 V min for Vin = 2.5 to 5.5 V, and the output is turned off when EN is low. |
| 4 | BP/Adj | passive | Bypass pin on fixed versions (a 470 pF capacitor to ground reduces output noise, may be left unconnected) and feedback/adjust pin on the adjustable version (Vref 1.27 V). |
| 5 | Vout | power_out | Regulated output delivering up to 600 mA, with output voltage accuracy of ±1.5% and current limit of 1300 mA typ. |
