SG7900A/SG7900 SERIES

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-M38510/11501BXA - JAN7905T

♦ MIL-M38510/11505BYA - JAN7905K

♦ MIL-M38510/11502BXA - JAN7912T

♦ MIL-M38510/11506BYA - JAN7912K

♦ MIL-M38510/11503BXA - JAN7915T

♦ 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.
