AZ1117CR-1.2TRG1 from Diodes Incorporated, in a SOT-89. 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 | Ground/adjust pin; for the fixed 1.2V version the adjust resistors are integrated, so this pin serves as GND, and in the ADJ version the adjust pin current is 60 µA typ and 120 µA max. |
| 2 | OUTPUT | power_out | Regulated 1.2V output (VOUT); the output capacitor must have ESR below 20Ω and a minimum of 10µF is required. |
| 3 | INPUT | power_in | Unregulated supply input (VIN) with an absolute maximum of 18 V and a recommended maximum of 15 V. |
