AP2205-50W5-7

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

AP2205-50W5-7 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 Unregulated supply input, 2.3V to 24V (absolute max 36V). Bypass to GND with a 1.0µF ceramic capacitor placed close to the pin.
2 GND power_in Device ground return. Typical ground current is 36µA at IOUT=100µA, rising to 2.5mA at IOUT=150mA.
3 EN input Enable input. VIH ≥ 2.0V turns the regulator on; VIL ≤ 0.4V forces the device into shutdown (standby current 0.01µA typ). EN input current 3µA typ; absolute max 36V.
4 NC unconnected Not connected on the fixed-voltage version (AP2205-50W5-7 is the 5.0V fixed variant). On the ADJ (adjustable) version this pin is ADJ, the feedback input tied to a resistor divider from VOUT (VREF=1.24V). Leave floating or tie to GND.
5 VOUT power_out Regulated 5.0V output, up to 200mA (VOUT>1.8V). Requires a 2.2µF ceramic output capacitor for stability. Dropout is 320mV typ at IOUT=100mA.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap2205-50w5-7.step 85 KB You want the bare part, or you mark your own boards.
ap2205-50w5-7-etched.step 2.3 MB You want the part with AP2205-50W5-7 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 554 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.
