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 P-TO252-5-1 (D-PAK) 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.
