# GS2401C-33CTR3

**Gainsil** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

GS2401C-33CTR3 from Gainsil, in a SOT-223-3. 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 | GND | power_in | Ground pin of the regulator, common return for input and output capacitors. |
| 2 | VOUT | power_out | Regulated output pin, with a 1µF to 10µF output capacitor and an absolute maximum of -0.3 to 6V to GND. |
| 3 | VIN | power_in | Power supply input pin, with an absolute maximum supply voltage of -0.3 to 44V and a 1µF input capacitor in the application circuit. |
