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

A common ground is required between the  
input and the output voltages. The input voltage  
must remain typically 2.0 V above the output  
voltage even during the low point on the input  
ripple voltage.
