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 P-DSO-14-8 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.
