SGM2203-12YK3G

SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

SGM2203-12YK3G from SGMICRO, in a SOT-89-3. 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 VOUT power_out Regulator output pin; use an output capacitor of 1µF to 10µF effective capacitance placed very close to this pin to ensure stability.
2 GND power_in Ground pin.
3 VIN power_in Regulator input pin, rated up to 36V; use a 1µF or larger ceramic capacitor from VIN to ground, placed as close as possible to the pin.
