LP2950-33LPE3 from Texas Instruments, in a TO-92-3. 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 | OUTPUT | power_out | Regulated 3.3V output (±1% accuracy −40°C to 125°C, 100mA maximum output current) requiring minimum 1μF capacitor to GND for stability. |
| 2 | GND | power_in | Ground reference. |
| 3 | INPUT | power_in | Input power supply pin supporting 2V to 30V input range with minimum 1μF bypass capacitor to GND recommended. |
