ATASHEET
DESCRIPTION
The SG78xxA/SG78xx series of
positive regulators offer self contained,
fixed-voltage capability with up to 1.5A of
load current and input voltage up to 50V
(SG78xxA series only). These units
feature a unique on-chip trimming system
to set the output voltages to within ±1.5%
of nominal on the SG78xxA series, ±2.0%
on the SG78xx series. The SG78xxA
versions also offer much improved line
and load regulation characteristics.
Utilizing an improved bandgap reference
design, problems have been eliminated
that are normally associated with the Zener
diode references, such as drift in output
voltage and large changes in the line and
load regulation.
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.
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. Product is
available in hermetically sealed TO-257
(both case grounded ‘G’ and isolated ‘IG’),
TO-3, TO-39 and LCC packages.

Note: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground. Currents are positive into, negative out of
specified terminal
.
Note 3: Operation at high input voltages is dependent upon load current. When load current is less than 5mA, output will rise out of regulation as input-
output differential increases beyond 30V. Note also from figure 1, that maximum load current is reduced at high voltages. The 50V input rating of the
SG78xxA series refers to ability to withstand 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.
