HG7133M3-1 from HGSEMI, in a SOT-23-3. 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 | GND | power_in | Ground reference return pin for the LDO. Connect to system single-point ground close to the input/output bypass capacitors. |
| 2 | VIN | power_in | Regulator input supply pin. Accepts up to 36V absolute maximum; place a ≥10uF polarized bypass capacitor as close to this pin as possible. |
| 3 | VOUT | power_out | Regulated +3.3V output pin (±2%), sourcing up to 100mA. Requires a ≥2.2uF (10uF recommended) output capacitor to ground for stability via ESR-based phase compensation. |
