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). |
