GS2301-18TR5

Gainsil · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

GS2301-18TR5 from Gainsil, in a SOT-23-5. 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 EN input Enable input: logic high requires at least 1.2V (referenced to VIN), logic low is 0.4V maximum, and the shutdown current is 1µA maximum with VEN = 0V.
4 NC unconnected No internal connection.
5 VOUT power_out Regulated output for the -18 variant, which is 1.8V per the ordering note (XX = 18); output current is up to 300mA and a 1µF capacitor is recommended.
