7133-1 from IDCHIP, in a SOT-89. 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; the SOT-89 pin drawing on page 2 shows pin 1 as GND. |
| 2 | VIN | power_in | Input supply pin, with a supply voltage range of -0.3V to +36V. |
| 3 | VOUT | power_out | Regulated 3.3V output pin (7133-1) rated for 100mA typical output current, which needs an output capacitor to ground larger than 2.2uF. |
