AP7343-12W5-7

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

AP7343-12W5-7 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 and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 VIN power_in Power input pin; recommended input range is 1.7V to 5.25V (6.0V absolute maximum), with a minimum 0.47µF ceramic capacitor to GND placed close to the device.
2 GND power_in Ground pin, to be connected to the external circuit ground.
3 EN input Enable pin that must be driven high or low and not left floating; high (≥1.3V) enables the regulator and low (≤0.5V) puts it into shutdown mode.
4 NC unconnected No connection.
5 VOUT power_out Regulated power output pin, fixed 1.2V for the AP7343-12W5-7 (non-discharge version), rated for up to 300mA output current.

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 assure input stability and reduce no 12

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: AP7343-12W5-7
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-25, generated on the KiCad land (body 1.6 x 3 mm, terminals on the pads, 1.1 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: ap7343-12w5-7-etched.step / ap7343-12w5-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7343-12w5-7.step / ap7343-12w5-7.glb are the bare package body.

  • Datasheet: Diodes Incorporated datasheet (20 pp, sha256 34e6b63381da732c, retrieved 2026-11-13, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
