# WL9005P3-30

**WPMtek Wei Pan Microelectronics** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L

WL9005P3-30 from WPMtek Wei Pan Microelectronics, in a SOT-89-3L. 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 | GND | power_in | Ground reference for the LDO. Return path for input and output capacitors; keep trace wide and short back to this pin for best transient/PSRR performance. |
| 2 | VIN | power_in | Unregulated power input, 2.0V to 7.0V operating range (9V absolute max). Requires a ≥1µF ceramic bypass capacitor to GND located close to the pin. In SOT89-3, the TAB is also VIN (thermally and electrically tied to this pin). |
| 3 | VOUT | power_out | Regulated output voltage pin. Fixed 3.0V for the WL9005P3-30 variant, ±1.5% accuracy, up to 500mA output current. Requires a ≥1µF (X7R/X5R) ceramic output capacitor to GND located close to the pin for stability. |
