SG7800A/SG7800 SERIES

05/01 Rev 1.4

DESCRIPTION

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.
