General Description
This device is a 5V low-drop fixed-voltage regulator. The maximum input voltage is 42V (65V, ≤ 4 00 ms). Up to an
input voltage of 26V and for an output current up to 550mA it regulates the output voltage within a 2% accuracy. The
short circuit protection limits the output current of more than 650mA. The device incorporates over voltage protection
and temperature protection that disables the circuit at un-permissibly high temperatures.
Features
TO-220-5L
Output Voltage tolerance ≤±2%
