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.
