Description
www.DataShTeheet4sUe.cormegulators employ internal current-limiting and thermal-shutdown,
making them essentially indestructible. They can deliver up to 500mA
output current, if the case temperature can be kept at 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
PL78M05XA3 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.
