OPTIREG Linear TLE4278G 5 V low drop fixed voltage regulator Features Output voltage tolerance 2% Very low current consumption Separated reset and watchdog output Low-drop voltage Watchdog Adjustable watchdog activating threshold Adjustable reset threshold Overtemperature protection Reverse polarity protection Short-circuit proof Suitable for use in automotive electronics Wide temperature range Green Product (RoHS compliant) Potential applications General automotive applications. Product validation Qualified for automotive applications. Product validation according to AEC-Q100/101. Description The OPTIREG Linear TLE4278G 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 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 TLE4278 can also be used in other applications where a stabilized voltage is required.
