DESCRIPTION
The SiP78LxxAC series of positive voltage regulators are
designed to provide a range of regulated power supply
voltages for low current applications of up to 100 mA.
They are low cost, rugged, easy to use, three terminal devices
with internal current limiting and thermal shutdown protection
and are the low current members of the popular SiP78Mxx and
SiP78xx family.
No external components are required with the SiP78LxxAC in
most applications.
These products offer an improved replacement for the
traditional zener-resistor combination, providing better output
impedance, lower internal power dissipation and lower
quiescent current.
