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, industrial power delivery and more.

The LM78Lxx with new chip is available in SOIC (D) package and SOT-89 (PK) package. 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.
