WILLSEMI Will Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

WL2863E28-5 from WILLSEMI Will Semicon, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input voltage supply pin (2.2 V to 5.5 V operating; abs max -0.3 V to 6.0 V). Requires a 1 µF ceramic capacitor to GND placed within 1 cm of the pin.
2 GND power_in Common ground / device return connection.
3 EN input Chip enable input. VEN < 0.4 V disables the regulator and engages the ~300 Ω active output discharge; VEN > 1.2 V enables the LDO. EN input current is typ. <1 µA over 0 to 5.5 V. Absolute voltage range: -0.3 V to VIN + 0.3 V.
4 NC unconnected No internal electrical connection. Leave floating or tie to GND per board convention.
5 VOUT power_out Regulated 2.8 V output (±2%), 250 mA max, with typ. 115 mV dropout at 250 mA. Requires a 1 µF ceramic capacitor to GND placed within 1 cm of the pin; stable with 1 µF ceramic input/output caps and no separate noise-bypass capacitor.
