Functional Description
This 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
unpermissibly high temperatures.
