SGM2034-3.3YN3G

SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

SGM2034-3.3YN3G from SGMICRO, in a SOT-23-3. 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 pin for the regulator.
2 OUT power_out Regulator output; a ceramic capacitor with effective capacitance of 0.1μF to 10μF should be placed as close as possible to this pin for decoupling.
3 IN power_in Input supply pin, operating from 1.7V to 7.5V; use a 1μF or larger ceramic capacitor from IN to ground, placed as close as possible to the pin.
