The OPTIREG™ Linear TLE4269GL is an automotive voltage regulator with a 5 V fixed output in a PG‑DSO‑20 package. The maximum operating voltage is 45 V. The output is able to drive a 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. The reset and sense outputs have integrated pull-up resistors. If the integrated resistors are not required, the TLE4279, a product version without the reset and sense output pull-up resistors can be used. The TLE4279 is available in PG-DSO-8 as the TLE4279GM and PG-DSO-14 as TLE4279GM.
It is also possible to supervise the input voltage by using an integrated comparator to give a low voltage warning.
The TLE4269 is also available in a PG‑DSO‑8 package as TLE4269G and in a PG‑DSO‑14 package as TLE4269GM.
