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. |

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.
