Application Information
Figure 3 Application Circuit: Output Voltage < Reference Voltage
Figure 3 shows a typical application circuit with
V
Q
< V
REF
. Of course, also V
Q
= V
REF
is
feasible by directly connecting the reference pin of the TLE 4252 D to the appropriate
voltage level without voltage divider.
The output voltage calculates to:
(1)
AEA03535.VSD
Main µC Supply
e.g.
TLE 4271-2
TLE 4278
TLE 4470
