WL9005HS5-28

WPMtek(Wei Pan Microelectronics) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

WL9005HS5-28 from WPMtek(Wei Pan Microelectronics), in a SOT-23-5L. 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 VIN power_in Input pin; the operating input voltage range is 1.2V to 6.0V and VIN to GND is rated -0.3V to 6V.
2 GND power_in Ground pin, the reference for the VIN (-0.3V to 6V), VOUT (-0.3V to 5V) and EN (-0.3V to 6V) ratings to GND.
3 EN input Enable pin; EN high is 0.83V minimum to enable the output and EN low is 0.78V maximum to shut it down.
4 NC unconnected No connection; the datasheet assigns no electrical function to this pin.
5 VOUT power_out Output pin; fixed output voltage with output current up to 500mA, and VOUT to GND is rated -0.3V to 5V.
