1.0 A Positive Voltage
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
• Available in Surface Mount D2PAK−3, DPAK−3 and Standard
3−Lead Transistor Packages
• NCV Prefix for Automotive and Other Applications Requiring Site
and Control Changes
• Pb−Free Packages are Available

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.

connected to Pin 2.
Pin 1. Input
2. Ground D2T SUFFIX
Heatsink surface (shown as terminal 4 in
case outline drawing) is connected to Pin 2.
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
XX, These two digits of the type number
indicate nominal voltage.
* Cin is required if regulator is located an
appreciable distance from power supply
** CO is not needed for stability; however,
it does improve transient response. Values
of less than 0.1 mF could cause instability.
