Functional Description
The TLE 4271-2 is functional and electrical identical to
TLE 4271.
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.
