Three Terminal Medium Current
Positive Voltage Regulators
LM78M05L3
SOT-223
Description
These regulators 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
LM78M05L3 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.
