# LM1086IT-5.0

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

LM1086IT-5.0 from Texas Instruments, in a TO-220. 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 pin for the fixed output voltage versions, which includes the LM1086-5.0 (the adjust function applies only to the adjustable version). |
| 2 | VOUT | output | Output voltage pin for the regulator; the TO-220 tab is also tied to output, and the maximum input-to-output differential for the LM1086-5.0 is 25 V. |
| 3 | VIN | power_in | Input voltage pin for the regulator, with a maximum input-to-output voltage differential of 25 V for the LM1086-5.0. |
