SGM2210-3.3XN5G

SGMICRO · Linear Voltage Regulators (LDO) · SOT-23-5

SGM2210-3.3XN5G 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 Input supply voltage pin (2.5V to 20V operating); use a 2.2μF or larger ceramic capacitor to ground placed as close as possible to this pin.
2 GND power_in Ground.
3 EN input Enable pin; drive high (above 1.3V) to turn on the regulator and low (below 0.4V) to turn it off.
4 NC unconnected No connection (fixed voltage version only).
5 OUT power_out Regulator output pin; use a ceramic capacitor with effective capacitance of 1μF to 22μF placed as close as possible to this pin to ensure stability.
