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 PL78L08 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.
