SGM2211-3.3XN5G

SGMICRO · Pre-Ordered Products · SOT-23-5

SGM2211-3.3XN5G 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 VIN power_in Input voltage supply pin; the input range is 2.7V to 20V, and a ceramic capacitor with at least 1.5µF effective capacitance should be connected from VIN to ground for decoupling.
2 GND power_in Ground pin for the regulator.
3 EN input Enable pin: drive high to turn the regulator on and low to turn it off, with precision EN thresholds of VIH 1.120V to 1.295V and VIL 1.050V to 1.195V.
4 NC unconnected No connection on the fixed-voltage version of the device (NC is listed for the fixed version only).
5 VOUT power_out Regulator output pin; a ceramic output capacitor with 1.5µF to 10µF effective capacitance should be placed as close as possible to this pin for stability.
