WL9005HS3-25

WPMtek Wei Pan Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

WL9005HS3-25 from WPMtek Wei Pan Microelectronics, in a SOT-23-3. 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 GND power_in Ground pin; the datasheet's SOT23-3 figure labels this pin GND, and the absolute maximum rating for VIN to GND is -0.3 V to 6 V.
2 VOUT power_out Output pin, with VOUT to GND rated -0.3 V to 5 V and output current up to 500 mA, limited internally by current limit and short circuit protection.
3 VIN power_in Input pin, with operating input voltage of 1.2 V to 6.0 V and VIN to GND rated -0.3 V to 6 V; a 1 uF ceramic input capacitor is recommended between VIN and GND.
