SGM2033-3.3XN5G

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

SGM2033-3.3XN5G from SGMICRO, in a SOT-23-5. 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 IN power_in Input voltage supply pin. Operating range 1.8V to 5.5V. Bypass to GND with a 1µF ceramic capacitor (0.1µF min effective) close to the pin.
2 GND power_in Ground reference for the regulator.
3 EN input Enable pin. Drive EN high (VIH ≥ 1.5V) to turn on the regulator, low (VIL ≤ 0.4V) to turn off. Has an internal 0.2µA pull-down current source that ensures shutdown when floated. Must be tied to IN if enable functionality is not used.
4 NC unconnected Not connected (fixed voltage version only). May be left floating or tied to GND.
5 OUT power_out Regulated 3.3V output pin. Use an output capacitor with effective capacitance in the range of 0.5µF to 10µF located very close to this pin. Output current capability 250mA (500mA typ current limit).
