Functional Description
This device is a 5-V low-drop fixed-voltage regulator.
The maximum input voltage is 42 V (65 V, f 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 device
incorporates overvoltage protection and temperature
protection that disables the circuit at unpermissibly
high temperatures.
