L4940V12

VERY LOW DROP 1.5 A REGULATORS

STMicroelectronics 

L4940 series

Figure 26 : Distributed Supply with On-card L4940 and L4941 Low-drop Regulators.

ADVANTAGES OF THESE APPLICATIONS ARE :

On card regulation with short-circuit and thermal protection on each output.

Very high total system efficiency due to the switching preregulation and very low-drop postregulations.

Figure 27.

ADVANTAGES OF THIS CONFIGURATION ARE :

Very high regulation (line and load) on both the output voltages.

12 V output short-circuit and thermally protected.

Very high efficiency on the 12 V output due to the very low drop regulator.
