# 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. |
