The LM78L series (LM78Lxx throughout this document) of positive linear regulators is available with several fixed output voltages, making the devices useful in a wide range of applications. Used as a Zener-diode and resistor combination replacement, the LM78Lxx typically provides an effective output impedance improvement of two orders of magnitude and lower quiescent current. These regulators can provide local, on-card regulation, eliminating distribution problems associated with single-point regulation. The available voltages allow the LM78Lxx to be used in logic systems, instrumentation, HiFi, and other solid-state electronic equipment.

The LM78Lxx with new chip is available in SOIC (D) package and SOT-89 (PK) packages. The LM78Lxx series regulators can deliver up to 100mA output current. Current limiting is included to limit the peak output current to a safe value. If internal power dissipation is too high, the thermal shutdown circuit prevents the IC from overheating.
