Voltage Regulators -
Positive
1.0 A
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.
Features

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.
XX, These two digits of the type number
indicate nominal voltage.
* Cin is required if regulator is located an
appreciable distance from power supply
filter.
** CO is not needed for stability; however,
it does improve transient response. Values
of less than 0.1 mF could cause instability.
