SK6011D4-30

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

SK6011D4-30 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 Regulated output pin; bypass with a 1μF ceramic capacitor from this pin to ground.
2 GND power_in Ground.
3 EN input Enable control input, active high (VIH 1.2V min, VIL 0.4V max); do not leave EN floating.
4 IN power_in Supply input (1.9V to 5.5V); 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).
