SK6018D4-30 from Suntek, in a DFN1x1-4L. 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 | output | Regulated LDO output, with output range 1.2V to 3.6V in 0.1V steps and output current up to 300mA at VIN-VOUT=0.5V (absolute maximum output current 350mA). |
| 2 | GND | power_in | Ground reference pin for the regulator; the datasheet also lists the thermal pad as GND. |
| 3 | EN | input | Active-high enable that must not be left floating; VENH is at least 1.2V and VENL is at most 0.4V, with an input current of 1.0µA maximum. |
| 4 | VIN | power_in | Power input with a recommended supply range of 2.5V to 6.5V and an absolute maximum input voltage of -0.3V to 8V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
