AZ1084CD-1.8TRG1 from Diodes Incorporated, in a TO-252. 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 | Pin 1 is the ADJ pin on the adjustable version and the GND pin on fixed versions such as the 1.8V AZ1084C-1.8, which is ground. |
| 2 | OUTPUT | power_out | Regulated output (1.8V for the -1.8 version, up to 5A load current, 6.5A typical current limit) with a 22µF output capacitor shown in the typical application circuit. |
| 3 | INPUT | power_in | Unregulated input voltage, recommended maximum 12V (absolute maximum 13.2V), with a 10µF input capacitor shown in the typical application circuit. |
