# GS2301-33TR3

**Gainsil** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-3

GS2301-33TR3 from Gainsil, in a SOT23-3. 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 | VIN | power_in | Input supply pin; the recommended supply range is 2.5V to 6.5V, and the absolute maximum input voltage is -0.3V to 8V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | VOUT | power_out | Regulated output pin; the output is 1.8V to 3.6V in 0.1V steps (3.3V for the GS2301-33 variant), with output current up to 300mA and a recommended 1μF capacitor. |
