WPMtek(Wei Pan Microelectronics) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
WL9015S5-33 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 | Power input pin with an operating input voltage range of 2.5V to 24V, decoupled with a 1µF or larger ceramic capacitor placed close to the device. |
| 2 | GND | power_in | Ground pin that serves as the return for input and output capacitors, connected with as wide and short a copper trace as practical. |
| 3 | EN | input | Enable control input where CE high voltage is at least 1.5V and CE low voltage is at most 0.4V, with the output turned off when low. |
| 4 | NC | unconnected | No connect pin that is not internally connected to the device. |
| 5 | VOUT | power_out | Regulated output voltage pin, which for this -33 variant is 3.3V, requiring an output capacitor of at least 1µF ceramic (X7R or X5R) placed close to the pin. |
