LM1117IDT-ADJ from Texas Instruments, in a TO-252. 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 of the adjustable-output version (ground pin on fixed-output versions), which can receive transient signals of ±25 V relative to the output voltage without damaging the device, and can be bypassed to ground for improved ripple rejection. |
| 2 | VOUT | power_out | Regulator output pin, also connected to the TAB; a tantalum output capacitor of at least 10 µF with ESR between 0.3 Ω and 22 Ω is required for stability, and 22 µF is needed when a bypass capacitor is used on ADJ. |
| 3 | VIN | power_in | Regulator input pin with a recommended input voltage of at most 15 V (VIN to GND) and an absolute maximum of 20 V, where an input capacitor (10 µF tantalum) is recommended. |
