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.
