OPTIREG Linear TLE4279 5V low drop fixed voltage regulator Features Output voltage tolerance 2% 150 mA current capability Very low current consumption Early warning Reset output low down to V = 1 V Q Overtemperature protection Reverse polarity proof Adjustable reset threshold Very low-drop voltage Wide temperature range Green Product (RoHS compliant) Potential applications General automotive applications. Product validation Qualified for Automotive Applications. Product Validation according to AEC-Q100/101 Description The OPTIREG Linear TLE4279 is an automotive voltage regulator with a 5 V fixed output, in a PG-DSO-8 or PG-DSO-14 package. The maximum operating voltage is 45 V. The output is able to drive 150 mA load. The device features short-circuit protection. The thermal shutdown feature switches the output off when the junction temperature exceeds 150C to ensure the device is not damaged by overheating. A reset signal is generated when the output voltage drops below V < 4.65 V. The reset threshold voltage can be decreased by Q an external connection of a voltage divider. The reset delay time can be set by an external capacitor. If the application requires pull-up resistors at the logic outputs (Reset, Sense Out) the TLE4269 with integrated resistors can be used. It is also possible to supervise the input voltage by using an integrated comparator to give a low voltage warning.
