What are the key features of LM1086T-ADJ?
- Adjustable output voltage from 1.25 V to 29 V set by two external resistors
- Low dropout voltage of 1.5 V at 1.5 A full load current
- Current limiting and thermal shutdown protection built in
What is LM1086T-ADJ used for?
The LM1086T-ADJ is well suited for post-regulation in battery-powered portable equipment, set-top boxes, and DSP or FPGA core-supply rails where a stable, adjustable low-noise supply is needed. Its low dropout characteristic makes it ideal for 5 V to 3.3 V conversion and other applications with minimal headroom. The TO-220 package provides good thermal dissipation for continuous 1.5 A loads in bench instruments and industrial control boards.

Frequently Asked Questions
What output voltage range can the LM1086T-ADJ regulate to?
The LM1086T-ADJ covers an adjustable output range of 1.25 V to 29 V, set by two external resistors connected between the ADJ and output pins. This flexibility makes it a versatile choice for supplying 1.8 V, 2.5 V, 3.3 V, or 5 V rails from a single part.
How much continuous output current does the LM1086T-ADJ support in a 5 V to 3.3 V conversion design?
The LM1086T-ADJ delivers up to 1.5 A of continuous output current. At this full load, the dropout voltage is 1.5 V, so a 5 V input rail provides comfortable headroom when generating a 3.3 V output, making this regulator a practical drop-in for logic and microcontroller supply rails.
Which protection features are integrated in the LM1086T-ADJ to safeguard the end application?
The LM1086T-ADJ includes internal current limiting and thermal shutdown protection. Current limiting prevents damage if the output is shorted, while thermal shutdown triggers above approximately 150 °C junction temperature, protecting both the device and surrounding PCB components during fault conditions.
When would the LM1086T-ADJ be a better choice than a fixed-voltage LDO such as the LM1086-3.3?
The LM1086T-ADJ is preferable when the target output voltage is not one of the standard fixed options or needs field trimming. A single adjustable part covers 1.25 V to 29 V, reducing SKU count in multi-rail designs and allowing fine-tuning with 1% resistors to within a few millivolts of the desired setpoint.
