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.
