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
• No External Components Required
• Internal Thermal Overload Protection
• Internal Short Circuit Current Limiting
• Output Transistor Safe−Area Compensation
• Output Voltage Offered in 1.5%, 2% and 4% Tolerance
• Available in Surface Mount D

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.

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.
