TO-92 (Top View)
This series of fixed-voltage monolithic integrated-cir-
cuit 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 fea-
tures of these regulators make them essentially im-
mune to overload. When used as a replacement for
a Zener diode-resistor combination, an effective im-
provement in output impedance can be obtained to-
gether 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.
