1.0 A Positive Voltage
Regulators
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
1.0 A. Although designed primarily as a fixed voltage regulator, these
devices can be used with external components to obtain adjustable
voltages and currents.
