UTC Unisonic Tech · Voltage Reference · TO-252
LP2950L-3.3V-1 from UTC Unisonic Tech, in a TO-252. 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 | INPUT | power_in | Unregulated supply input (VIN) to the regulator; absolute maximum supply voltage is -0.3 to +30 V. |
| 2 | GND | power_in | Ground reference for the regulator. |
| 3 | OUTPUT | power_out | Regulated 3.3 V output (VOUT, ±2% accuracy) delivering up to 100 mA. |
