Product details

Fixed 8.5 V rail for automotive subsystems

The Infineon TLE4274GV85-2 is a single-output positive fixed LDO regulator delivering 8.5 V at up to 400 mA. It is qualified to AEC-Q100, making it a fit for automotive power rails — sensor supplies, CAN transceiver bias, or ECU local regulation. The PG-TO263-3-1 package (D²Pak, 3 leads plus tab) is a surface-mount power package sized for the 400 mA load with the tab soldered to the board copper for heat removal.

Quiescent current and protection suite

Quiescent current is 220 µA typical, which matters for always-on modules where the regulator itself is a standing load. The part includes antisaturation, over-temperature shutdown, reverse polarity protection, and short-circuit protection — built-in ruggedness that saves external clamp diodes and supervisory ICs in an automotive BOM.

Frequently asked questions

Is TLE4274GV85-2 obsolete?

No. The product status is Active — no discontinuation or last-time-buy notice is in effect.

Is TLE4274GV85-2 compatible with TLE4274G?

The TLE4274G family shares the same PG-TO263-3-1 footprint and pinout. Compatibility depends on the output voltage variant — the GV85-2 is fixed at 8.5 V, so confirm that the other variant's output matches your rail.

Can TLE4274GV85-2 be used in automotive applications?

Yes. It is AEC-Q100 qualified and rated for a junction temperature range of -40°C to 150°C, covering under-hood and engine-bay environments.
