Ordering Code
Q67006-A9291
Package
P-DSO-14-4 (SMD)
Functional Description
The TLE 4278 is a monolithic integrated low-drop fixed-voltage regulator which can
supply loads up to 200 mA. The device is available in the P-DSO-14-4 package. It is
designed to supply microprocessor systems under the severe conditions of automotive
applications and therefore is equipped with additional protection functions against over
load, short circuit and over temperature. Of course 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_Qrated = 5 V within an
accuracy of ± 2%.
The device operates in the wide temperature range of T_j = – 40 to 150 °C.
