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.
