AZ1117H-ADJTRE1 from Diodes Incorporated, in a SOT-223. 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 | input | Adjust pin for the adjustable version (AZ1117-ADJ); connect to the R1/R2 feedback divider to set VOUT = VREF*(1+R2/R1)+IADJ*R2, where VREF=1.25V and IADJ typ 60 uA. Serves as GND on fixed-output variants. |
| 2 | OUTPUT | power_out | Regulated output; delivers up to 1A. Requires >=22 uF output capacitor for stability. On SOT-223 the output pin is electrically connected to the tab (VOUT). |
| 3 | INPUT | power_in | Unregulated input supply; VIN(max) = 20V absolute, 15V recommended. Requires >=10 uF input capacitor. Dropout is 1.15V typical at 1A. |
