TX78L XXis three terminal positive regulators.
One of these regulators can deliver up to 100 mA
of output current. The interal limiting and thermal
-shutdown features of the regulator make them
essentially immune to overload. When used as a replacement for a zener diode-resistor
Combination, an effective improvement in output
impedance can be obtained, together with lower
quiescent current.
