DESCRIPTION

The L79L00 series of three-terminal positive

regulators employ internal current limiting and

thermal

shutdown, making them

essentially

indestructible. If adequate heatsink is provided,

they can deliver up to 100 mA output current.

They are intended as fixed voltage regulators in a

wide range of applications including local or

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.

The L79L00 series used as Zener diode/resistor

combination replacement, offers an effective

output impedance improvement of typically two

orders of magnetude, along with lower quiescent

current and lower noise.
