PG-SSOP-14 EP
Description
The TLE4291 is a monolithic integrated low-dropout voltage regulator in a PG-SSOP-14 EP exposed pad
package, especially designed for automotive applications. An input voltage up to 42 V is regulated to an output
voltage of 5.0 V. The component is able to drive loads up to 450 mA. It is short-circuit protected by the
implemented current limitation and has an integrated overtemperature shutdown. The integrated reset and
watchdog function makes it suitable for supplying microprocessor systems in automotive environments. The
watchdog and the power-on reset delay timing can be programmed by the external delay capacitor.
