SG7800A/SG7800 SERIES
SG7800A/SG7800
POSITIVE FIXED VOLTAGE REGULATOR
DESCRIPTION
FEATURES
The SG7800A/SG7800 series of positive regulators offer self contained,
fixed-voltage capability with up to 1.5A of load current and input voltage up
to 50V (SG7800A series only). These units feature a unique on-chip
trimming system to set the output voltages to within±1.5% of nominal on the
SG7800A series,±2.0% on the SG7800 series. The SG7800A 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, TO-3, TO39 and LCC
packages.
Output voltage set internally to ±1.5% on SG7800A
