HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92-3
LM2950G-5.0 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 5.0 V output; the datasheet guarantees 100 mA output current and requires a low-ESR ceramic output capacitor for stability. |
| 2 | GND | power_in | Ground reference pin; ground current is 75 uA typ (120 uA max) at 100 uA load and 3 mA typ (12 mA max) at 100 mA load. |
| 3 | VIN | power_in | Unregulated input supply; the absolute maximum input voltage is 30 V (VIN from -0.3 V to 30 V) and the minimum input is VOUT + 1 V for regulation. |
