SGM2203-5.0YK3LG

SGMICRO SGM2203 5 0YK3LG TR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

SGM2203-5.0YK3LG from SGMICRO SGM2203 5 0YK3LG TR, in a SOT-89-3. 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 GND power_in Ground reference for the regulator.
2 VIN power_in Regulator input pin. Accepts up to 36V input voltage (recommended 2.7V to 36V). Requires a 1μF or larger ceramic decoupling capacitor to ground, placed as close as possible to the pin.
3 VOUT power_out Regulated 5.0V output pin, capable of sourcing up to 150mA. Requires an output capacitor with effective capacitance in the 1μF to 10μF range for stability, placed close to the pin.
