Product details

15 V fixed output, 500 mA capacity

The 1 V maximum dropout at 50 mA means the input rail must stay above 16 V to maintain regulation, a typical margin for 18 V or 24 V industrial supplies. Built-in protection covers over-temperature, reverse polarity, and short-circuit events — no external clamp diode needed for reverse-battery scenarios up to 26 V max input.

Industrial temp range and quiescent current

The 2 mA quiescent current (20 mA max supply) keeps the idle draw low enough for always-on systems.
