LP2950G-50-T92-K

UTC Unisonic Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92

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.
