ap2204k-adjtrg1.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 5 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

AP2204K-ADJTRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

AP2204K-ADJTRG1 from Diodes Incorporated, in a SOT-23-5. 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 Supply input voltage. Recommended operating range 2.6V to 24V (absolute max 38V). Bypass with a 1.0µF ceramic capacitor to GND close to the pin. Minimum VIN must be the larger of 2.6V or VOUT+1V to avoid dropout.
2 GND power_in Device ground reference. Substrate connection; must be tied to system ground.
3 EN input Enable input. Logic high (VIH >= 2.0V) turns the regulator on; logic low (VIL <= 0.4V) puts the device in standby (ISTD ~0.01µA typ, 1.0µA max). Absolute maximum VCE = 38V. Do not leave floating.
4 ADJ input Adjust feedback input for the ADJ (adjustable) version. Connect to the tap of an external R1/R2 divider from VOUT to GND; VOUT = VREF x (1 + R1/R2) where VREF = 1.24V typ (1.215V-1.265V). ADJ pin bias current IADJ = 0.5µA typ at IOUT = 100µA.
5 VOUT power_out Regulated output voltage, programmable 1.24V-22V via the ADJ divider. Delivers up to 150mA (typ current-limit ~700mA). Bypass to GND with a 2.2µF low-ESR ceramic capacitor for stability and load-transient response.

CAD (KiCad official)

  • Symbol: AP2204K-ADJTRG1
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ap2204k-adjtrg1-etched.step / ap2204k-adjtrg1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap2204k-adjtrg1.step / ap2204k-adjtrg1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap2204k-adjtrg1.step 85 KB You want the bare part, or you mark your own boards.
ap2204k-adjtrg1-etched.step 2.3 MB You want the part with AP2204K-ADJTRG1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 582 faces against 102 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.
