SK6018D4-33

Suntek · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · XDFN-4-EP(1x1)

SK6018D4-33 from Suntek, in a XDFN-4-EP(1x1). 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 VOUT power_out Regulated LDO output, programmable from 1.2V to 3.6V in 0.1V steps (3.3V for this -33 version), rated for up to 300mA per the features list with a 350mA current limit.
2 GND power_in Ground reference for the regulator, connected to the thermal pad.
3 EN input Active-high enable input that must not be left floating; VENH is 1.2V minimum and VENL is 0.4V maximum, with input current up to 1.0µA.
4 VIN power_in Power input with a recommended supply range of 2.5V to 6.5V and an absolute maximum of -0.3V to 8V.
5 GND passive Exposed pad (from the footprint; not named in the datasheet pin table).
