AZ1117CD-5.0TRG1 from Diodes Incorporated, in a TO-252-2. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ADJ/GND | power_in | Adjust/ground pin: it is the ground reference on the fixed-output versions (including AZ1117CD-5.0), and on the ADJ version it is the adjust pin, which draws about 60 µA typical and 120 µA maximum. |
| 2 | OUTPUT | power_out | Regulated output; the datasheet requires a minimum 10µF output capacitor with ESR below 20Ω, and the output is held at 5.0 V ±1% (4.900 V to 5.100 V over temperature) for this version. |
| 3 | INPUT | power_in | Unregulated input supply; the absolute maximum input voltage is 18 V and the recommended maximum is 15 V, with at least about 1.3 V to 1.4 V of dropout required at 0.8 A on the TO252-2 package. |
