SGM2028-3.3YN5G

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

SGM2028-3.3YN5G 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 IN power_in Regulator input supply, which can range from 2.5V to 5.5V and should be bypassed with a 1µF capacitor to GND.
2 GND power_in Ground reference pin for the regulator.
3 EN input Shutdown input where a logic low reduces the supply current to 10nA, and it should be connected to IN for normal operation.
4 BP passive Reference-noise bypass for the fixed-voltage version, which should be bypassed with a low-leakage 0.01µF ceramic capacitor to reduce output noise.
5 OUT power_out Regulator output that delivers up to 500mA guaranteed output current.
