AP7343Q-18W5-7

Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-25

AP7343Q-18W5-7 from Diodes Incorporated, in a SOT-25. 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 of the regulator, which must be decoupled to GND with a minimum 0.47μF ceramic capacitor per the application information.
2 GND power_in Ground pin; the regulator ground should be connected to the external circuit ground to reduce voltage drop from trace impedance.
3 EN input Enable pin that must be driven either high or low and must not be floating; driving it high enables the regulator and pulling it low puts the regulator into shutdown mode.
4 NC unconnected No connect, not connected internally; the datasheet recommends connecting it to GND to maximize PCB copper for thermal dissipation.
5 VOUT power_out Regulated power output pin; short-circuit protection clamps the output current to approximately 60mA when shorted to GND.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper capacitor is recommended between VIN and GND pins to decouple input power supply glitch. This input capacitor must be located as close as possible to the device to ensure input stability and reduce no 11
