SUL6018D4-33

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

SUL6018D4-33 from Suntek, in a DFN-4L(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 output pin, fixed 0.8V to 4.5V in 0.05V steps with ±1% accuracy, sourcing up to 350mA.
2 GND power_in Ground pin.
3 EN input Chip enable pin that turns the regulator on or off, with 0.05µA shutdown current.
4 VIN power_in Input supply pin, operating range 1.2V to 5.5V.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
