Positive Fixed Voltage Regulator
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.
