Options
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

Available in Surface Mount Package
These units feature a unique band gap increased through the use of a simple
reference which allows the SG79xxA voltage divider. The low quiescent drain

Note: 1. C1 is required only if regulator is separated from
rectifier filter.
Note: C3 optional for improved transient response and ripple
rejection.
2. Both C1 and C2 should be low E.S.R. types such
as solid tantalum. If aluminum electrolytic
capacitors are used, at least 10 times values
shown should be selected.
3. If large output capacities are used, the regulators
must be protected from momentary input shorts. A
