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.
