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.
Output Current in Excess of 1.0 A
No External Components Required
Internal Thermal Overload Protection
Internal Short Circuit Current Limiting
Output Transistor Safe–Area Compensation
Output Voltage Offered in 2% and 4% Tolerance

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.
