Key Features
- AEC-Q100 automotive-grade 5 V fixed LDO with 250 mV typical dropout for efficient automotive rail regulation
- Wide input voltage range from 8 V to 42 V handling 12 V and 24 V automotive battery rails including load dump
- 45 V absolute maximum input rating protecting against automotive transients in a compact 5-pin TO-252 package
Applications
The TLE4275QKTTRQ1 is designed for automotive body control modules, ADAS sensors, and infotainment units that require a stable 5 V logic supply derived from a 12 V or 24 V vehicle battery. Its 42 V maximum input voltage and AEC-Q100 qualification make it suitable for power conditioning in harsh under-hood environments where voltage spikes during load dump and cold-crank conditions are common.

Frequently Asked Questions
What dropout voltage and input range does the TLE4275QKTTRQ1 provide for automotive 5 V regulation?
The TLE4275QKTTRQ1 has a typical dropout voltage of 250 mV and a maximum of 500 mV, accepting input voltages from 8 V to 42 V, which allows reliable 5 V output regulation from a 12 V automotive battery even during cold-crank conditions when the battery voltage dips below 9 V.
How does the TLE4275QKTTRQ1's 45 V absolute maximum rating protect automotive ECUs from transients?
Automotive load-dump transients can spike to 40 V or beyond on the 12 V battery rail; the TLE4275QKTTRQ1's 45 V absolute maximum input rating ensures the regulator survives these events without damage, protecting the downstream 5 V logic supply for microcontrollers and sensors inside the ECU.
Which automotive system designs benefit from using TLE4275QKTTRQ1 versus a standard industrial LDO?
Body control modules, gateway ECUs, and ADAS camera power supplies benefit from TLE4275QKTTRQ1 because its AEC-Q100 Grade 1 qualification, -40°C to +125°C operating range, and 42 V input capability meet automotive OEM requirements that a standard industrial LDO rated below 20 V cannot satisfy.
