LP2950G-50-T92-K from UTC Unisonic Tech, in a TO-92. 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 5.0 V output (LP2950G-50) within ±2%, delivering up to 100 mA with a typical current limit of 215 mA and requiring CL = 1 µF in the datasheet test conditions. |
| 2 | GND | power_in | Ground reference for the input and output of the regulator. |
| 3 | INPUT | power_in | Unregulated supply input, rated -0.3 to +30 V absolute maximum. |
