AZ1117CD-1.5TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2

AZ1117CD-1.5TRG1 from Diodes Incorporated, in a TO-252-2. 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 GND power_in Ground / regulator common reference. On the fixed-output (-1.5) variant the ADJ/GND pin functions as GND. Also thermally coupled to the exposed tab.
2 VOUT power_out Regulated 1.5V output. Requires a minimum 10µF output capacitor with ESR < 20Ω (low-ESR ceramic capacitor recommended). Current-limit typical 1.35A.
3 VIN power_in Unregulated input supply. Absolute-max 18V; recommended operating VIN ≤ 15V. Requires input decoupling (10µF typical). Must be ≥ VOUT + dropout (~1.3V @ 0.8A) for regulation.
4 TAB power_in Exposed metal tab on the TO252-2 package. Electrically connected internally to the OUTPUT pin and used as the primary thermal path - solder to a copper pour for heatsinking. NOTE: the tab is on VOUT, not GND (typical of LM1117-family DPAK regulators).
