SG7900A/SG7900 SERIES
SG7900A/SG7900
NEGATIVE FIXED VOLTAGE REGULATOR
DESCRIPTION
The SG7900A/SG7900 series of negative regulators offer self-contained,
fixed-voltage capability with up to 1.5A of load current. With a variety of
output voltages and four package options this regulator series is an
optimum complement to the SG7800A/SG7800, SG140 line of three
terminal regulators.
These units feature a unique band gap reference which allows the
SG7900A series to be specified with an output voltage tolerance of ±1.5%.
The SG7900A versions also offer much improved line regulation character-
istics.
All protective features of thermal shutdown, current limiting, and safe-area
control have been designed into these units and since these regulators
require only a single output capacitor (SG7900 series) or a capacitor and
5mA minimum load (SG120 series) for satisfactory performance, ease of
application is assured.
Although designed as fixed-voltage regulators, the output voltage can be
increased through the use of a simple voltage divider. The low quiescent
drain current of the device insures good regulation when this method is
used, especially for the SG120 series.
These devices are available in hermetically sealed TO-257, TO-3, TO-39
and LCC package.
