TECHNICAL DATA
POSITIVE VOLTAGE REGULATOR
3- TERMINAL 1A POSITIVE VOLTAGE REGULATORS
IL78xx
The IL78xx series of three-terminal positive regulators are
available in the TO-220, TO-252, TO-263 package and with
several fixed output voltage, marking them useful in a wide range
of applications. These applications include on-card regulation for
elimination of noise and distribution problems associated with
single point regulation with single point regulation. In addition,
they can be used with power pass elements to make high current
voltage regulators. If adequate heat sinking is provided, each of
these regulator can deliver over 1A of output current. Although
designed primarily as fixed voltage regulators, these devices can
be used with external components to obtain adjustable voltage
and currents.

Fixed Output Regulator
Notes:
1. To specify an output voltage, substitute voltage value for “XX.” A common ground is required between the input and the output
voltage. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input ripple voltage.
2. CI is required if regulator is located an appreciable distance from power supply filter.
3. CO improves stability and transient response.
