Suntek · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · XDFN-4-EP(1x1)
SK6013AD4-12 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; the recommended operating output current is below 300 mA and the absolute maximum output current is 550 mA. |
| 2 | GND | power_in | Ground pin of the regulator; the DFN1x1-4L top view also labels the package thermal pad as GND. |
| 3 | EN | input | Enable input, active high; the datasheet states it must not be left floating. |
| 4 | VIN | power_in | Power input; recommended supply voltage is 2.5 V to 6.5 V, with an absolute maximum input voltage of -0.3 V to 8 V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
