SG7800A/SG7800 SERIES

SG7800A/SG7800

POSITIVE FIXED VOLTAGE REGULATOR

DESCRIPTION

FEATURES

The SG7800A/SG7800 series of positive regulators offer self contained,

• Output voltage set internally to ±1.5% on SG7800A

fixed-voltage capability with up to 1.5A of load current and input voltage up • Input voltage range to 50V max. on SG7800A

to 50V (SG7800A series only). These units feature a unique on-chip • Two volt input-output differential

trimming system to set the output voltages to within±1.5% of nominal on the

SG7800A series,±2.0%ontheSG7800series. TheSG7800Aversionsalso

• Excellent line and load regulation

• Foldback current limiting

offer much improved line and load regulation characteristics. Utilizing an • Thermal overload protection

improved Bandgap reference design, problems have been eliminated that • Voltages available: 5V, 12V, 15V

are normally associated with the Zener diode references, such as drift in • Available in surface mount package

output voltage and large changes in the line and load regulation.

HIGH RELIABILITY FEATURES

- SG7800A/7800

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 small output capacitor for satisfactory performance, ease of

application is assured.

♦ Available to MIL-STD - 883

♦ MIL-M38510/10702BXA - JAN7805T

♦ MIL-M38510/10703BXA - JAN7812T

♦ MIL-M38510/10704BXA - JAN7815T

♦ MIL-M38510/10706BYA - JAN7805K

♦ MIL-M38510/10707BYA - JAN7812K

♦ MIL-M38510/10708BYA - JAN7815K

♦ Radiation data available

Although designed as fixed-voltage regulators, the output voltage can be

increased through the use of a simple voltage divider. The low quiescent

draincurrentofthedeviceinsuresgoodregulationwhenthismethodisused.

Product is available in hermetically sealed TO-257, TO-3, TO39 and LCC

packages.

♦ LMI level "S" processing available
