AP2205-W5-7

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

AP2205-W5-7 from Diodes Incorporated, in a SOT-25. 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 2.3V to 24V; absolute maximum 36V. Requires ~1.0μF ceramic input capacitor to GND.
2 GND power_in Device ground reference. All bypass capacitors and the feedback divider return here.
3 EN input Enable input. VIH ≥ 2.0V turns the regulator on; VIL ≤ 0.4V puts the part in shutdown (standby current ~0.01μA typ, 1μA max). Absolute max 36V. Typical EN pin current ~3μA at VEN = VOUT+1V.
4 ADJ input Adjustable-version feedback input. Connect to the mid-point of an external resistor divider from VOUT to GND; VOUT = VREF × (1 + R1/R2), where VREF = 1.24V typ (1.215V-1.265V). Typical ADJ pin current 0.5μA. On fixed-voltage variants of the SOT25 package this pin is NC (not connected).
5 VOUT power_out Regulated output voltage. Delivers up to 200mA (150mA for VOUT ≤ 1.8V). Requires ~2.2μF ceramic output capacitor to GND; low-ESR ceramic compatible.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ap2205-w5-7.step 85 KB You want the bare part, or you mark your own boards.
ap2205-w5-7-etched.step 1.8 MB You want the part with AP2205-W5-7 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 456 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.

Provenance
