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). |
