DESCRIPTION
The SG78xxA/SG78xx series of All protective features of thermal
positive regulators offer self contained, shutdown, current limiting, and safe-area
fixed-voltage capability with up to 1.5A of control have been designed into these units
load current and input voltage up to 50V and since these regulators require only a
