DESCRIPTION
The SG79xxA/SG79xx series of negative control have been designed into these units
regulators offer self-contained, fixed- and since these regulators require only a
voltage capability with up to 1.5A of load single output capacitor (SG79xx series) or a
current and input voltage up to -30V. With capacitor and 5mA minimum load (SG120
