• Manufacturer Part Number: L4940
• Description: VERY LOW DROP 1.5 A REGULATORS
• Manufacturer: 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.
