These regulators employ internal current-limiting and thermal-
TO-92
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 H7805_A 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.
