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 650 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 a temperature protection which turns off the device at high temperatures.
1) ESD susceptibility, Human Body Model (HBM) according to EIA/JESD 22-A114B
