Applications
• Battery-Powered Circuitry
• Post Regulator for Switching Power Supply
This series of fixed-voltage monolithic integrated-circuit voltage regulators is designed for a wide range
of applications. These applications include on-card
regulation for elimination of noise and distribution
problems associated with single-point regulation. In
addition, they can be used with power-pass elements
to make high-current voltage regulators. Each of
these regulators can deliver up to 100mA of output
current. The internal limiting and ternal shutdown features of these regulators make them essentially immune to overload. When used as a replacement for
a Zener diode-resistor combination, an effective improvement in output impedance can be obtained together with lower-bias current.

Note1 : A common ground is required between the input and the output voltage. The input voltage must
remain typically 2V above the output voltage even during the low point on the input ripple voltage.
Note2 : Cin is required if regulator is located an appreciable distance from power supply filter.
Note3 : C
is not needed for stability; however, it does improve transient response.
