AZ1084CD-1.8TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

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.
