WPMtek Wei Pan Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

WL9005S5-30 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. Operating range 2.0 V to 7.0 V (absolute max -0.3 V to +9 V). Decouple with a ≥1 µF ceramic capacitor to GND, placed as close to the pin as possible.
2 GND power_in Device ground reference. Return path for input and output decoupling capacitors; route back to this pin with wide, short copper for best transient and PSRR performance.
3 EN input Enable/shutdown control input. Logic high (VCEH ≥ 1.2 V) turns the regulator on; logic low (VCEL ≤ 0.4 V) disables the LDO and puts the output in fast-discharge, ~0 A shutdown state. Absolute max -0.3 V to +9 V; IEN typ 0.01 µA. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to GND for mechanical stability; do not use as a routing tie-point.
5 VOUT power_out Regulated output voltage (3.0 V fixed for the -30 variant, ±1.5% accuracy). Sources up to 500 mA with 600 mV typical dropout at 500 mA. Requires a ≥1 µF X5R/X7R ceramic output capacitor to GND placed close to the pin for stability.
