DESCRIPTION
These three terminal positive regulators approved by DESC, are supplied in
a hermetically sealed isolated, metal TO-257 package. All protective features
are designed into the circuit including thermal shutdown, current limiting and safearea control. With heat sinking, they can deliver over 3.0 amps of output current.
These units feature 1% and 2% initial voltage tolerance, 0.35% load regulation and
.01% line regulation.
