For calculation of resistor R
7
:
V
IN
, input voltage :
V
INmin
= 8V,
V
EXTmin
= 6V,
I
R7min
= 1mA,
V
INmax
= 16V
V
EXTmax
= 9V
I
R7max
= 6mA
V
EXT
:
I
R7
, input current :
To get lower power dissipation the value of resistor R
7
should also be as high as
possibile. For this reason we use R
7max
. If in the calculation above R
7min
is higher than
R
7max
, then the input voltage range is not correct; V
INmax
-V
INmin
is too large.
Note:
If V
INmin
= 6V and V
INmax
= 9V then the resistor R
7
is not necessary. The input
voltage V
IN
can directly be connected to V
EXT
.
