POSITIVE VO L TAGE REGULATOR
3- TERMINAL 1A POSITIVE VOLTA GE REGULATORS
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 r ange
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.
FEATURES
• Output current up to 1A
• No external components required
• Internal short circuit current limiting
• Intermal thermal overload protection
• Output transistor safe-area compensation
• Output voltage offered in 4% tolerance
