Key Features
- Fixed 5 V output with 500 mA load capability and ultra-low 0.3 V typical dropout voltage minimizes power dissipation in automotive LDO designs
- Wide 5.6 V to 45 V input voltage range tolerates automotive load dump transients and cold-crank conditions without external protection
- AEC-Q100 qualified automotive grade ensures reliability across -40°C to +125°C junction temperature range in harsh in-vehicle environments
- 12-pin MSOP-EP package with exposed pad provides enhanced thermal dissipation for sustained 500 mA output in compact automotive PCB layouts
Applications
The LT3065EMSE-5#PBF is designed for automotive ECU power rails, infotainment system local regulators, and ADAS sensor supply circuits requiring a stable 5 V output from a 12 V or 24 V vehicle bus. Its 45 V maximum input rating accommodates load-dump transients common in 12 V automotive systems without requiring additional clamping components. The MSOP-EP package suits space-constrained automotive control modules including body electronics, instrument clusters, and gateway modules operating across a -40°C to +125°C temperature range.

Frequently Asked Questions
What is the input voltage range and dropout voltage of the LT3065EMSE-5#PBF?
The LT3065EMSE-5#PBF accepts input voltages from 5.6 V to 45 V with an absolute maximum of 50 V, making it tolerant of automotive load-dump transients. Its typical dropout voltage is only 0.3 V at 500 mA output, minimizing the required headroom between input and the fixed 5 V output rail.
Which automotive ECU designs benefit from the LT3065EMSE-5#PBF 5 V LDO?
The LT3065EMSE-5#PBF suits automotive gateway ECUs, body control modules, and ADAS sensor power supplies that derive a stable 5 V rail from a 12 V vehicle battery bus. Its AEC-Q100 qualification and -40°C to +125°C operating range ensure long-term reliability in underhood and cabin electronics exposed to wide thermal cycling.
How does the MSOP-EP package improve thermal performance for the LT3065EMSE-5#PBF at full load?
The 12-pin MSOP-EP (exposed pad) package of the LT3065EMSE-5#PBF conducts heat through the exposed thermal pad directly to the PCB copper pour, reducing junction-to-board thermal resistance compared to standard MSOP packages. This enables the LT3065EMSE-5#PBF to sustain 500 mA output current with a 10 V dropout without exceeding the 125°C junction temperature limit on a 2-layer PCB.
Is the LT3065EMSE-5#PBF an alternative to adjustable LDOs in fixed 5 V automotive supply designs?
Yes, the LT3065EMSE-5#PBF eliminates the external resistor divider required by adjustable LDOs such as the LT3080, reducing component count and improving output accuracy to within ±2% of 5 V across -40°C to +125°C. This fixed-output simplicity is preferred in automotive designs where BOM reduction and assembly yield are priorities over output voltage flexibility.
