SGM2203-3.3YN3LG

SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

SGM2203-3.3YN3LG from SGMICRO, in a SOT-23-3. 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 Device ground reference. Connect to the system ground plane; ground pin current is typically 4.2 µA (no load).
2 VOUT power_out Regulator output pin, fixed at 3.3 V for this ordering option and capable of sourcing up to 150 mA. Place a 1 µF to 10 µF ceramic output capacitor as close to this pin as possible to ensure loop stability.
3 VIN power_in Regulator input pin, accepting 2.7 V to 36 V (32 V max for VOUT < 3.3 V options). Decouple with a ≥1 µF ceramic capacitor placed as close as possible to this pin for good PSRR.
