STANDARD APPLICATION
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.

appreciable distance from power supply

CO
is not needed for stability; however,
it does improve transient response. Values
of less than 0.1 µF could cause instability.

These voltage regulators are monolithic integrated circuits designed as
xed–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 xed voltage regulator, these devices can be used with
external components to obtain adjustable voltages and currents.

O due to heating eects must be taken into account
separately. Pulse testing with low duty cycle is used.
