Sandy punk likes this. Liniar voltage regulator are indeed simple to use and provide unmatchable noise rejection but are highly ineficient. The prices are exl. Question about IC Sockets Posted by droggie in forum: As long as the panel generates adequate voltage and current the only advantage to higher efficiency is to reduce or eliminate the need for a heatsink datashert may be a sufficient reason.

Sep 24, 2, You need a 12V, 2A, low dropout regulator such as this. Your panel provides 18 volts at 40 watts.

So with an input voltage of lower than 14 Volts, the output voltage will drop. Valuable comments will be rewarded. Prices for items, which are not held in our stock can be different from indicated ones.

Hello, Keep in mind that the L regulator needs 2 to 2. Or do you have any interesting comments? Try sites like Polou.

Even 1 W is a lot of power that is dissipated as heat. I wouldnt worry to supply directly to the pump. IC Question Posted by datxsheet in forum: Did you come across any error? When high currents are needed above 1 amp it’s better to use dc-dc converters. Aug 5, 5. Would you like to change anything? Just guessing here, but if you run catasheet motor directly from the PVP Photo Voltaic Panel the loading of the motor will likely drop the voltage down quite a bit.
