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 over
voltage protection and temperature protection that disables the circuit at overtemperature.
Type TLE4271-2G
Package PG-TO263-7
