\subsection{LM317}
|
|
As the viewfinder needs its own power supply, I need 7V from 12V. Parts box has LM317.
|
|
|
|
\begin{verbatim}
|
|
Formula for LM317:
|
|
Vout = 1.25 * (1+ R2/R1)
|
|
|
|
R1 = vout to gndpin
|
|
R2 = gndpin to gnd
|
|
|
|
e.g. 720 R2, 240 R1 == 5V
|
|
1K R2 == 6.45V
|
|
1.1K R2 == 6.97V
|
|
|
|
\end{verbatim}
|
|
\textbf{Standard R1 is 240ohm}, so let's keep to the standard.\footnote{Check when looking through devices that use LM317, which adhere to that standard. They should, when possible. Standards should always be followed.}
|
|

Make sure to \underline{account for the drop out} needed for Vin to LM317.
