Diodes Incorporated AP2204K 3 3TRG1 · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
AP2204K-3.3TRG1 from Diodes Incorporated AP2204K 3 3TRG1, 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 maximum 38V. Bypass with 1.0uF ceramic capacitor to GND close to the pin. |
| 2 | GND | power_in | Device ground reference. Ground current is ~50uA at IOUT=100uA and ~1.3mA at IOUT=100mA. |
| 3 | EN | input | Active-high enable input. VIH >= 2.0V enables the regulator; VIL <= 0.4V puts the device in shutdown. EN input current is ~1uA typical; absolute maximum EN voltage is 38V. |
| 4 | NC | unconnected | Not connected internally on the fixed-voltage version (AP2204K-3.3). Diodes recommends tying to GND to maximize PCB copper for thermal dissipation. (On the ADJ variant this pin is the ADJ feedback input.) |
| 5 | VOUT | power_out | Regulated 3.3V output. Rated for up to 150mA continuous (absolute max 250mA). Requires a 2.2uF ceramic output capacitor for stability. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 626 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.
