3-TERMINAL POSITIVE VOLTAGE REGULATOR

Description

TO-92

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 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.
