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.","metaTitle":"Infineon TLE4274GV85-2 LDO Regulator, 8.5V Fixed, 400mA","metaDescription":"Infineon TLE4274GV85-2 fixed 8.5V LDO regulator, 400mA output, 0.5V dropout at 250mA, 60dB PSRR at 100Hz.
