LM78L05ACMX

Product Summary

The LM78L05ACMX is a three terminal positive regulator. It is available with several fixed output voltages making them useful in a wide range of applications. When used as a zener diode/resistor combination replacement, the LM78L05ACMX usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. The LM78L05ACMX can provide local on card regulation, eliminating the distribution problems associated with single point regulation. The voltages available allow the LM78L05ACMX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. The LM78L05ACMX is available in the plastic TO-92 (Z) package, the plastic SO-8 (M) package and a chip sized package (8-Bump micro SMD) using National micro SMD package technology. With adequate heat sinking the regulator can deliver 100 mA output current. Current limiting is included to limit the peak output current to a safe value. Safe area proprotection for the output transistors is provided to limit internal power dissipation. If internal power dissipation of the LM78L05ACMX becomes too high for the heat sinking provided, the thermal shutdown circuit takes over preventing the IC from overheating.
