Description
These regulators employ internal current-limiting and thermal-shutdown,
making them essentially indestructible. They can deliver up to 100mA
output current. if the case temperature can keep in Tc=25°C.
They are intended as fixed voltage regulators in a wide range of applications
including local (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 LM78L05 used as a Zener diode/resistor combination
replacement, offers an effective output impedance improvement
of typically two orders of magnitude, along with lower quiescent current
and lower noise.

Note:
C1 and C2 are required if regulator is
located far from power supply filter
and load, or oscillation may induced
on the loop.
