# GS2401C-33STR3

**Gainsil** · Linear Voltage Regulators (LDO) · SOT89-3

GS2401C-33STR3 from Gainsil, in a SOT89-3. 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 reference pin; the EN-to-GND voltage is limited to -0.3 to 44 V and the VOUT-to-GND voltage to -0.3 to 6 V. |
| 2 | VIN | power_in | Power supply input with a recommended range of 2.5 V to 40 V and an absolute maximum of -0.3 to 44 V. |
| 3 | VOUT | power_out | Regulated output with ±1% accuracy, delivering a minimum of 150 mA maximum output current in SOT89-3, and limited to -0.3 to 6 V relative to GND. |
