These voltage regulators are monolithic integrated circuits designed

as fixedïvoltage regulators for a wide variety of applications

including local, onïcard regulation. These regulators employ internal

current limiting, thermal shutdown, and safeïarea compensation. With

adequate heatsinking they can deliver output currents in excess of

1.0 A. Although designed primarily as a fixed voltage regulator, these

devices can be used with external components to obtain adjustable

voltages and currents.
