Gainsil · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23
GS431-TR from Gainsil, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REF | input | Reference input. Compared internally against the 2.5V bandgap; drives the shunt element when VREF is exceeded. Typical reference current 0.7uA, max input current 10mA. |
| 2 | CATHODE | passive | Cathode of the shunt regulator. Sinks 1-100mA to regulate the node to the programmed voltage (VREF to 36V). Absolute max VKA = 40V, IKA = -100 to 150mA. |
| 3 | ANODE | passive | Anode of the shunt regulator; normally tied to circuit ground / low-side return. |
