Fixed Voltage Regulator
Descriptions
This series of fixed-negative-voltage monolithic integrated-circuit voltage regulators is
designed to complement series S7800 in a wide range of applications. These applications
include on-card regulator for elimination of noise and distribution problems associated with
single point regulations. Each of these regulators can deliver up to 1.0 amperes of output
current. The internal current Limiting and thermal shutdown features of these regulators
make them essentially immune to overload. In addition to use as fixed-voltage regulators,
these device can be used with external components to obtain adjustable output voltages
and also as the power pass element in precision regulators.

Pulse testing techniques are used to maintain the junction temperature as close to the ambient
temperature as possible. Thermal effects must be taken into separately.
