What are the key features of LT3085IMS8E#TRPBF?
- Adjustable output from 0 V to 36 V with 500 mA current rating
- Ultra-low 0.275 V typical dropout enabling near-rail output regulation
- Paralleling capability to scale current beyond 500 mA without ballast resistors
- Automotive-grade construction in 8-pin MSOP with exposed pad for thermal efficiency
What is LT3085IMS8E#TRPBF used for?
The LT3085IMS8E#TRPBF is suited for automotive ECU power stages, industrial sensor supplies, and lab bench-style adjustable rail generation where output voltage must be programmable from ground up to 36 V. Its current-output architecture allows multiple units to be paralleled directly, scaling total output current for loads exceeding 500 mA in motor driver pre-stages or multichannel analog supply rails. The MSOP exposed pad reduces junction temperature in thermally constrained automotive and industrial PCB environments.

Frequently Asked Questions
What output voltage range does the LT3085IMS8E#TRPBF support and how is it set?
The LT3085IMS8E#TRPBF supports an adjustable output voltage from 0 V up to 36 V, set by a single external resistor from the SET pin to ground. Unlike traditional LDOs that reference a fixed internal bandgap, the LT3085 uses a current-output reference architecture that allows the output to be programmed down to 0 V, enabling rail-to-rail adjustable supplies for test equipment, motor drives, and automotive ECU power stages requiring flexible voltage configuration.
How does the paralleling feature of LT3085IMS8E#TRPBF benefit high-current applications?
Multiple LT3085 devices can be connected in parallel with their outputs tied together and matched SET resistors, sharing load current equally without external ballast resistors. Two units in parallel deliver 1 A total, three deliver 1.5 A, and so on, with current matching better than 2% typical. This feature is valuable in automotive power distribution modules or precision analog supply banks where a single 500 mA regulator is insufficient but a larger discrete pass transistor circuit would be more complex and less accurate.
What is the dropout voltage of the LT3085IMS8E#TRPBF and why does it matter for automotive designs?
The LT3085IMS8E#TRPBF has a typical dropout voltage of 0.275 V and a maximum of 0.45 V at 500 mA. In automotive cold-crank scenarios where battery voltage can sag to 6 V or 7 V, the low dropout allows the regulator to maintain a 5 V output with only 0.45 V headroom, keeping microcontrollers and sensors powered through engine start events. The 1 V minimum input-output differential sets the practical lower boundary for full regulation.
How does the exposed pad in the MSOP-8E package improve thermal performance for the LT3085IMS8E#TRPBF?
The exposed metal pad on the underside of the MSOP-8E package bonds directly to a PCB copper thermal plane during reflow, lowering the junction-to-board thermal resistance by 3x to 5x compared to a standard MSOP without the exposed pad. At 500 mA output with 5 V dropout, the device dissipates 2.5 W, which the exposed pad helps conduct away to maintain junction temperature below 125°C in automotive ambient conditions reaching 85°C, enabling sustained full-load operation without heatsink clips.
