WL9005S5-25 from WPMtek Wei Pan Microelectronics, in a SOT-23-5L. 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 VIN power_in Power input. Recommended operating range 2.0 V to 7.0 V (absolute max -0.3 V to +9 V). Connect a ≥1 µF ceramic bypass capacitor from VIN to GND as close as possible to the pin to decouple supply noise/glitches.
2 GND power_in Device ground reference. Return path for input/output capacitors; route back to the WL9005 GND pin with a wide, short copper trace to minimize parasitic inductance/resistance and preserve transient performance.
3 EN input Enable (chip-enable) control input. VCEH ≥ 1.2 V asserts enable (regulator ON); VCEL ≤ 0.4 V holds the device in shutdown (ISHDN ≈ 0 µA). EN absolute-maximum range -0.3 V to +9 V; input current IEN ≈ 0.01 µA typ. Do not leave floating - tie to VIN for always-on operation or drive from logic/pushbutton for on/off control.
4 NC unconnected No-connect. Leave floating or tie to GND; not internally bonded to any active circuitry.
5 VOUT power_out Regulated output voltage. Fixed 2.5 V for the -25 option (Vout accuracy ±1.5%, i.e. Vout×0.985 to Vout×1.015). Delivers up to 500 mA; current-limit ILIMIT ≈ 650 mA, short-circuit current ISHORT ≈ 100 mA. Requires a ≥1 µF ceramic output capacitor (X7R/X5R) placed close to VOUT and GND for LDO stability and transient response.
