SK1117-1.2

Shikues · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

SK1117-1.2 from Shikues, in a SOT-223-4. 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 VSS/ADJ power_in Ground (VSS) pin for the fixed-output SK1117-1.2 variant. On the ADJ variant this same pin becomes the ADJ feedback input. Reference for the internal 1.25V bandgap; connect to the single-point ground of the application.
2 VOUT power_out Regulated 1.2V output (1.176V min, 1.224V max, tested with Vin=2.5V, 0<=Iout<=1A). Requires a ~10uF tantalum bypass capacitor to ground for stability. Rated for up to 1A continuous load current.
3 VIN power_in Unregulated input supply, typically 2.5V for the 1.2V version and up to 15V typ / 18V absolute max. Requires a ~10uF tantalum bypass capacitor to ground. Dropout is 1.1V typ at 1A.
4 VOUT power_out SOT-223 tab / large output pad, internally connected to pin 2 VOUT. Provides thermal dissipation path - solder to a copper pour to lower the ~20°C/W package thermal resistance.
