These voltage regulators are monolithic integrated circuits designed as fixed
voltage regulators for a wide variety of applications including local, on-card
regulation. These regulators employ internal current limiting, thermal shutdown,
and safe-area compensation. With adequate heatsinking they can deliver output
currents in excess of 1.0A. Although designed primarily as fixed voltage regulator,
these devices can be used with external components to obtain adjustable
voltages and currents.
