SGM2209-5.0XN5G

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

SGM2209-5.0XN5G 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 GND power_in Ground.
2 VIN power_in Input voltage supply pin (-2.7V to -24V, most negative potential); use a 2.2μF or larger ceramic capacitor from VIN to ground placed as close as possible to the pin.
3 EN input Enable pin: drive EN 2.0V above or below ground to turn on the regulator, drive to ground to turn it off, or connect to VIN for automatic startup.
4 NC unconnected Not connected (fixed voltage version; this pin is ADJ on the adjustable version only).
5 VOUT power_out Regulator output pin; use a ceramic capacitor with effective capacitance of 1.5μF to 10μF placed as close as possible to the pin.
