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.

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.

**

Output

These two digits of the type number

indicate nominal voltage.

C in is required if regulator is located an

appreciable distance from power supply

filter.

C O is not needed for stability; however,

it does improve transient response. Values

of less than 0.1 m F could cause instability.
