1.0 A Positive Voltage
Regulators
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.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
*This device series contains ESD protection and exceeds the following tests:
Human Body Model 2000 V per MIL_STD_883, Method 3015.
Machine Model Method 200 V.
