HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92-3

LM2950G-3.3 from HTC Korea TAEJIN Tech, 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 VOUT power_out Regulated output of the LM2950G-3.3, which needs a low-ESR ceramic output capacitor for stability and is rated for 100 mA output current.
2 GND power_in Ground reference pin for the regulator.
3 VIN power_in Unregulated input supply, with an absolute maximum input voltage of 30 V (-0.3 V to 30 V) and a recommended maximum of 30 V.
