WPMtek Wei Pan Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
WL9005S5-33 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 | Supply input, operating range 2.0 V to 7.0 V, absolute maximum -0.3 V to 9 V, and a ≥1 µF ceramic input capacitor should be placed as close to the device as possible. |
| 2 | GND | power_in | Ground reference for the regulator; the input and output capacitor grounds must return to this pin through a wide, short copper trace. |
| 3 | EN | input | Enable control input with absolute maximum rating of -0.3 V to 9 V, where VEN ≥ 1.2 V enables the output and VEN ≤ 0.4 V disables it. |
| 4 | NC | unconnected | No connect pin with no internal connection on the SOT23-5L package. |
| 5 | VOUT | power_out | Regulated output, adjustable in the 0.8 V to 5.0 V range (3.3 V for the -33 variant), requiring a ≥1 µF ceramic output capacitor (X7R or X5R) placed close to VOUT and GND. |
