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.
Features
•Output Current in Excess of 1.0 A

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.

Input
Cin*
0.33 mFCO**
Output
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.
