Functional Description
The TLE 4271-2 is functional and electrical identical to
the 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
P-TO220-7-12
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.
