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.

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

µF could cause instability.

Three-Terminal 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.
