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 150°C to ensure the device is not damaged by overheating. A reset signal is generated when the output voltage drops below VQ < 4.65 V. The reset threshold voltage can be decreased by 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.
