AP2303MPTR-G1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · ESOP-8

AP2303MPTR-G1 from Diodes Incorporated, in a ESOP-8. 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 Unregulated power input supply (1.2 V to 5.5 V operating). A small 10 µF MLCC should be connected from this pin to GND. Absolute max -0.3 to 6 V.
2 GND power_in Device ground return.
3 VREFEN input Reference voltage input and active-low shutdown control (0.6 V to VCNTL-2.2 V operating; typical 0.9/0.75/0.675/0.6 V). Pulling below ~0.15 V shuts the device off; releasing initiates a ~0.1 ms soft-start. Output VTT tracks VREFEN within ±10 mV.
4 VOUT power_out Regulated termination voltage output; sources and sinks up to ±1.75 A. Requires a minimum 10 µF ceramic capacitor to ground for stability.
5 NC unconnected No connection.
6 VCNTL power_in Control input supply for the internal control circuitry and pass-device drive (3.0 V to 5.5 V operating; typical 3.3 V or 5 V). Must be kept ≥ VIN during power-on/off sequences. Draws ~0.5 mA typical, ~30 µA in shutdown.
7 NC unconnected No connection.
8 NC unconnected No connection.
9 EP passive Exposed thermal pad (PSOP-8 only). Should be connected to the ground copper pour for improved heat dissipation.

CAD (KiCad official)

  • Symbol: AP2303MPTR-G1
  • Footprint: Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm
  • 3D model: ESOP-8 (KiCad packages3D, STEP)
  • 3D model files: ap2303mptr-g1-etched.step / ap2303mptr-g1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap2303mptr-g1.step / ap2303mptr-g1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap2303mptr-g1.step 125 KB You want the bare part, or you mark your own boards.
ap2303mptr-g1-etched.step 2.6 MB You want the part with AP2303MPTR-G1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 637 faces against 152 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
