AZ1117ID-ADJTRG1

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

AZ1117ID-ADJTRG1 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 Adjust pin of the ADJ version, which sources about 60 µA typical (120 µA max) into the reference divider; it serves as GND on the fixed-output versions.
2 OUTPUT power_out Regulated output; a minimum 10 µF output capacitor is required, with ESR below 20 Ω.
3 INPUT power_in Unregulated input supply; recommended maximum VIN is 15 V, with an absolute maximum of 18 V, and VIN must exceed VOUT by at least 1.5 V for regulation.
