This voltage regulator is a monolithic integrated circuit designed as a fixed-voltage regulator for a wide variety of applications including local, on-card regulation. This regulator employs internal current limiting, thermal shutdown, and safe-area compensation. With adequate heat sinking it can deliver output currents in excess of 1A. Although designed primarily as a fixed voltage regulator, this device can be used with external components to obtain adjustable voltages and currents.
