NEGATIVE FIXED VOLTAGE REGULATOR
DESCRIPTION
The SG120 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/
7800/120 line of three terminal regulators.
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 or a capacitor and 5mA minimum load for satisfactory
performance, ease of application is assured.
Although designed as fixed-voltage regulators, the output voltage can be in-
creased 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. Utilizing an improved Bandgap reference design, problems
have been eliminated that are normally associated with the zener diode refer-
ences, such as drift in output voltage and large changes in the line and load
regulation
These devices are available in TO-257 (hermetically sealed TO-220), both
isolated and non-isolated), TO-3, TO-39 and TO-66 power packages.

NOTE: 1. C1 is required only if regulator is separated from rectifier filter.
2. Both C1 and C2 should be low E.S.R. types such as solid
tantalum. If aluminum electrolitics 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 high current diode
from output to input will suffice.
NOTE: C3 optional for improved transient response and ripple
rejection.

Description
Key Features:
" Output current to 1.5A
" Excellent line and load regulation
" Foldback current limiting
" Thermal overload protection
" Voltages available: -5V, -12V, -15V
"Voltages Not Recommended For New
Designs: -5.2V, -8V, -18V, -20V
" Contact factory for other voltage
options
The SG120 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/7800/120 line of three terminal regulators.
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 or a capacitor and 5mA minimum load
for satisfactory performance, ease of application is assured.
Although designed as fixed-voltage regulators, the output voltage can be
in-creased 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. Utilizing an improved Bandgap reference
design, problems have been eliminated that are normally associated with the
zener diode references, such as drift in output voltage and large changes in
the line and load regulation
These devices are available in TO-257 (hermetically sealed TO-220), both
isolated and non-isolated), TO-3, TO-39 and TO-66 power packages.

the SG7800A/7800/120 line of three terminal regulators.
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 or a capacitor and 5mA minimum load
for satisfactory performance, ease of application is assured.
Although designed as fixed-voltage regulators, the output voltage can be
in-creased 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. Utilizing an improved Bandgap reference
design, problems have been eliminated that are normally associated with the
zener diode references, such as drift in output voltage and large changes in
the line and load regulation
These devices are available in TO-257 (hermetically sealed TO-220), both
isolated and non-isolated), TO-3, TO-39 and TO-66 power packages.

Description
Key Features:
" Output current to 1.5A
" Excellent line and load regulation
" Foldback current limiting
" Thermal overload protection
" Voltages available: -5V, -12V, -15V

options
The SG120 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/7800/120 line of three terminal regulators.
All protective features of thermal shutdown, current limiting, and safe-area
control have been designed into these units and since these regulators
