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

WL2808E12-5 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 Unregulated input supply, 2.5-5.5 V (absolute max 6.5 V). Bypass to GND with a 1 µF ceramic capacitor placed close to the pin.
2 GND power_in Device ground reference. Return path for input, output, and enable currents; tie directly to the system ground plane.
3 EN input Active-high enable. Drive ≥1.2 V (VENH) to enable the regulator, ≤0.4 V (VENL) to shut down (ISHDN < 1 µA). Input current ≤1 µA over 0-5.5 V; do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to GND for mechanical stability.
5 VOUT power_out Regulated 1.2 V output (WL2808E12-5 variant). Requires a 1 µF ceramic output capacitor to GND for stability; current-limited/short-circuit-protected via internal fold-back circuit.
