SG120
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.

SG120-08
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG120-08 with -55°C ≤ TA ≤ 150°C, and
VIN = -14V, IO = 5mA, CIN = 1.0mF, COUT = 1.0mF. Low duty cycle pulse testing techniques are used which maintains junction and case temperature equal
to the ambient temperature.)
