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.
