SGM2028-ADJYN5G

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

SGM2028-ADJYN5G from SGMICRO, 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 IN power_in Regulator input; supply voltage can range from 2.5V to 5.5V, and the input should be bypassed with a 1μF capacitor to GND.
2 GND power_in Ground reference pin for the regulator.
3 EN input Shutdown input; a logic low reduces the supply current to 10nA, and it should be connected to IN for normal operation.
4 FB input Feedback pin for the adjustable voltage version, used to set the output voltage of the device.
5 OUT power_out Regulator output.
