HG7525M3-1 from HGSEMI, in a SOT-23-3. 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 | GND | power_in | Ground reference pin for the regulator (引脚说明: 地). |
| 2 | VIN | power_in | Input pin; the supply voltage absolute maximum rating is -0.3 V to +30 V, and specified operation assumes VIN = VOUT + 2 V. |
| 3 | VOUT | power_out | Regulated output pin rated for up to 100 mA; the datasheet requires an output capacitor greater than 2.2 uF to ground, with 10 uF recommended placed close to the VOUT pin. |
