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-M38510/10708BYA - 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

CHARACTERISTIC CURVES
Note 3. Operationathighinputvoltagesisdependentuponloadcurrent. When
load current is less than 5mA, output will rise out of regulation as input-
oiutput differential icreases beyond 30V. Note also from Figure 1, that
maximumloadcurrentisreducedathighvoltages. The50Vinputrating
of the SG140A series refers to ability to withstnd high line or transient
conditions without damage. Since the regulator's maximum current
capability is reduced, the output may fall out of regulation at high input
voltages under nominal loading.
