SGM2202-3.3YN5G

SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

SGM2202-3.3YN5G 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 supply voltage pin; the datasheet recommends a 1μF or larger ceramic capacitor from VIN to ground placed as close as possible to the pin, and the recommended input voltage range is 2.7V to 36V.
2 GND power_in Ground pin.
3 EN input Enable pin: drive high to turn the regulator on and low to turn it off, and it must be connected to VIN if enable functionality is not used.
4 BP passive Reference-noise bypass pin; an external CBP capacitor reduces output noise and should be placed very close to the pin for high PSRR.
5 VOUT power_out Regulator output pin; the datasheet recommends an effective output capacitance of 1μF to 10μF located very close to this pin.
