Bonjour,
Je suis à la recherche d'un traducteur pour APPLICATIONS INFORMATION
Negative side of the load.Although it may not be immediately obvious,best load regulation is obtained when the top of the resistor divider,R1,is connected directly to the case not to the load.This is illustraded (pièce jointe).
If R1 were connected to the load,the effective resistance between the regulator and the load would be:
R2+R1
Rp[ ------],Rp= Parasitic Line Resistance
R1
Connected as shown, Rp is not multiplied by the divider ratio.Rp is about 0.004ohms per foot using 16 gauge wire.This translates to 4mV/ft at 1A load curent,so it is important to keep the positive lead between regulator and load as short as possible,and use large wire or PC board traces.
Merci de bien vouloir me répondre en français,car je manque vraiment de vocabulaire technique.
Encore merci d'avance.
