SG7900A/SG7900  
NEGATIVE FIXED VOLTAGE REGULATOR  
DESCRIPTION  
FEATURES  
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.  
Output voltage set internally to ±1.5% on SG7900A  
Output current to 1.5A  
Excellent line and load regulation  
Foldback current limiting  
Thermal overload protection  
Voltages available: -5V, -12V, -15V  
Contact factory for other voltage options  
Available in surface mount package  
These units feature a unique band gap reference which allows the  
SG7900A series to be specified with an output voltage tolerance of±1.5%.

HIGH RELIABILITY FEATURES  
- SG7900A/SG7900  
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.  
Available to MIL-STD - 883

MIL-M38510/11507BYA - JAN7915K  
LMI level "S" processing available  
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.
