TLE4271-2

OPTIREG™ linear TLE4271-2 5-V low drop fixed voltage regulator Features Output voltage tolerance ≤ ±2% Low-drop voltage Integrated overtemperature protection Reverse polarity protection Input voltage up to 42 V Overvoltage protection up to 65 V (≤ 400 ms) Short-circuit proof Suitable for use in automotive electronics Wide temperature range Adjustable reset and watchdog time 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 TLE4271-2 is functional and electrical identical to TLE4271. The device is a 5-V low drop fixed voltage regulator. The maximum input voltage is 42 V (65 V, ≤ 400 ms). Up to an input voltage of 26 V and for an output current up to 550 mA it regulates the output voltage within a 2% accuracy. The short circuit protection limits the output current of more than 650 mA. The IC can be switched off via the inhibit input. An integrated watchdog monitors the connected controller. The device incorporates overvoltage protection and temperature protection that disables the circuit at overtemperature.
