**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

LM1086CT-ADJ from Texas Instruments, in a TO-220-3. 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 | Adjust pin for the adjustable output voltage version and ground pin for the fixed output voltage versions. |
| 2 | VOUT | power_out | Output voltage pin for the regulator. |
| 3 | VIN | power_in | Input voltage pin for the regulator; the maximum input-to-output voltage differential for the LM1086-ADJ is 29 V. |
