SK6512SS3-33

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

SK6512SS3-33 from Suntek, 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 reference pin for the regulator.
2 OUT power_out Regulated output pin; bypass with a 1 μF or greater ceramic capacitor from this pin to ground (OUT-to-GND absolute maximum is -0.3 to 6 V).
3 IN power_in Supply input pin; must be closely decoupled to GND with a 1 μF or greater ceramic capacitor (IN-to-GND absolute maximum is -0.3 to 40 V, input operating range up to 36 V).
