AZ1117CR-ADJTRG1 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 | passive | Adjust pin of the ADJ version, where the output is set by two external resistors and the adjust pin current is typically 60 µA and at most 120 µA (ground on the fixed-output versions). |
| 2 | OUTPUT | power_out | Regulated output of the AZ1117C, which requires a minimum 10 µF output capacitor with ESR less than 20 Ω. |
| 3 | INPUT | power_in | Unregulated input supply, rated 18 V absolute maximum and 15 V maximum under recommended operating conditions. |
