Functional Description

The TLE 4278 is a monolithic integrated low-drop fixed output voltage regulator

supplying loads up to 200 mA. The IC is available in a PG-DSO-14-30 package. It is

designed to supply microprocessor systems under the severe conditions of automotive

applications and therefore equipped with additional protection functions against over-

load, short circuit and overtemperature. The TLE 4278 can also be used in other

applications where a stabilized voltage is required.

An input voltage VI in the range of 5.5 V ≤ VI ≤ 45 V is regulated to VQ,nom = 5 V with an

accuracy of ±2%.

The device operates in the wide temperature range of Tj = -40 to 150 °C.

Two additional features are implemented in the TLE 4278 a load dependent watchdog

function as well as a sophisticated reset function including power on reset, under voltage

reset, adjustable reset delay time and adjustable reset switching threshold.
