ap2202k-3-3trg1.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

AP2202K-3.3TRG1

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

AP2202K-3.3TRG1 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 2.5V to 13.2V (absolute max 15V). For normal regulation VIN must be at least VOUT + 0.165V (dropout). A 1.0μF input capacitor (CIN) is recommended.
2 GND power_in Device ground and current return. Ground pin current is typically 95μA at IOUT=0μA and up to ~1.3mA at IOUT=150mA.
3 EN input Enable input, CMOS/TTL compatible. Logic high (VEN ≥ 2.0V) enables the regulator; logic low (VEN ≤ 0.4V) puts the device into low-power shutdown (ISTD ~0.01μA typ, 1μA max). Do not float; tie to VIN if always-on operation is desired. Absolute max VEN = 15V.
4 BYP passive Bypass pin for low-noise operation on the fixed-voltage (AP2202K-3.3) version. Connect an external capacitor (typ. 100pF) from BYP to GND to bypass the internal bandgap reference, reducing output noise (typ. 260 nV/√Hz with CBYP=100pF, COUT=2.2μF, IOUT=50mA). On the AP2202-ADJ variant this pin is instead ADJ (feedback input).
5 VOUT power_out Regulated output voltage, 3.3V ±1% (fixed for the -3.3 option). Delivers up to 150mA. Requires a 2.2μF output capacitor (COUT) for stability.

  • 3D model files: ap2202k-3-3trg1-etched.step / ap2202k-3-3trg1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap2202k-3-3trg1.step / ap2202k-3-3trg1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap2202k-3-3trg1.step 85 KB You want the bare part, or you mark your own boards.
ap2202k-3-3trg1-etched.step 2.6 MB You want the part with AP2202K-3.3TRG1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 639 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.
