Functional Description
The TLE 4284 is a monolithic integrated NPN type voltage regulator that can supply
loads up to 1.0 A. The chip is housed in a surface mounted PG-TO252-3-11 package
(DPAK). It is designed to supply microprocessor systems or other loads under the severe
conditions of automotive applications and therefore it is equipped with additional
protection against overload, short circuit and overtemperature.
An input voltage
V
I
in the range of (V
Q
+ V
DR
) < V
I
< 40 V is regulated to V
Q
. The dropout
voltage
V
DR
ranges from 1.1 V to 1.4 V depending on the load current level.
The device operates in the temperature range of
T
j
= -40 to 150 °C.
