WL2836D33-4

WILLSEMI(Will Semicon) · Linear Voltage Regulators (LDO) · DFN1x1-4L

WL2836D33-4 from WILLSEMI(Will Semicon), in a DFN1x1-4L. 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, which for WL2836D33-4 is 3.3V within the stated 0.9V~3.3V output range.
2 GND power_in Ground reference pin; the datasheet states that the exposed pad EP at GND level must also connect to GND.
3 EN input Active-high enable; the datasheet gives EN logic high at 1V minimum and EN logic low at 0.4V maximum.
4 VIN power_in Input supply pin with an operating input voltage range of 1.4V to 5.5V.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
