Used as a Zener-diode and resistor combination replacement, the LM78Lxx usually 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 …. PDF , 1. Extract from the document. The LM regulators are complete 3-terminal regulators requiring no external components fornormal operation.
However by adding a few parts one may improve the transient response provide for avariable output voltage or increase the output current. Included on the chip are all of t. Each section includes an example to increase the understandab.
PDF , 75 Kb , File published: May 8, The power limitations of the physical packaging for a linear regulator device can limit the total output current or the input-to-output voltage differential.
This inherent limitation is not always apparent from the product data sheet and must be evaluated during the design phase. This application note shows how the package can limit the operating envelope of a linear regulator.
