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
V
I
in the range of 5.5 V ≤ V
I
≤ 45 V is regulated to V
Q,nom
= 5 V with an
accuracy of ±2%.
The device operates in the wide temperature range of
T
j
= -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.
