# SK6011D4-33

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

SK6011D4-33 from Suntek, in a DFN-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 | OUT | power_out | Output pin; bypass with a 1µF ceramic capacitor from this pin to ground. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable control input, active high; do not leave EN floating. |
| 4 | IN | power_in | Supply input pin; must be closely decoupled to GND with a 1µF or greater ceramic capacitor. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
