What are the key features of TL720M05QKTTRQ1?
- Fixed 5 V output with input range 5.5 V to 42 V and maximum 0.5 V dropout voltage for automotive power rails
- AEC-Q100 qualified for automotive-grade reliability in under-hood and body electronics environments
- TO-263 3-pin package with low thermal resistance enabling robust power delivery in space-constrained automotive PCBs
What is TL720M05QKTTRQ1 used for?
TL720M05QKTTRQ1 is designed for automotive ECU, body control module, and infotainment power supply circuits requiring a stable regulated 5 V rail from a 12 V or 24 V vehicle battery bus. Its wide 5.5 V to 42 V input tolerance handles load dump transients common in automotive systems, and the AEC-Q100 qualification assures reliability over the full automotive temperature range. The TO-263 surface-mount package supports high-current 5 V regulation with direct PCB thermal sinking.

Frequently Asked Questions
What is the input voltage range of TL720M05QKTTRQ1 and how does it handle automotive load dump conditions?
The TL720M05QKTTRQ1 accepts input voltages from 5.5 V to 42 V, with an absolute maximum of 45 V, making it capable of surviving automotive load dump transients that can spike a 12 V battery bus well beyond 40 V. The fixed 5 V output with a maximum dropout of 0.5 V ensures stable regulation even as the battery bus fluctuates between 6 V and 40 V during engine cranking and load switching events.
Which automotive subsystems are best served by the TL720M05QKTTRQ1 regulated 5 V output at AEC-Q100 grade?
Body control modules, ADAS sensor power rails, instrument cluster microcontrollers, and CAN transceiver supply lines all benefit from a stable 5 V regulated output qualified to AEC-Q100 Grade 1 standards. The device operates reliably across the -40°C to +125°C automotive temperature range, making it suitable for under-hood and body electronics requiring long service lifetimes of 10 or more years in harsh environments.
How does the TO-263 package of TL720M05QKTTRQ1 help manage thermal dissipation in automotive power supply designs?
The TO-263 surface-mount package provides a large exposed drain pad that transfers heat directly into a PCB copper pour, enabling thermal dissipation without a separate heatsink. For a 12 V input to 5 V output conversion at 500 mA load, power dissipation is approximately 3.5 W, and the TO-263 package with a copper pour allows junction temperatures to stay within the 125°C automotive rated limit across the -40°C to +85°C ambient range.
