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

LM2950GTA-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 3.3 V output, guaranteed up to 100 mA of output current, and the datasheet requires a low-ESR ceramic output capacitor for stability.
2 GND power_in Ground reference pin; ground current is 75 µA typ. (120 µA max.) at 100 µA load and 3 mA typ. (12 mA max.) at 100 mA load.
3 VIN power_in Unregulated input supply with an absolute maximum rating of -0.3 V to 30 V, and dropout is 380 mV typ. at 100 mA output (450 mV max.).
