How I can drop the 12 - 14v battery for my bike to a source of constant 7.4v?
I'm trying to drop the voltage from the battery my bike to a source of constant 7.4v. I am currently dealing with a voltage regulator 12 V and a voltage divider, is close to the works that gives me about tensions from 6.8 to 8.1, however I need to get as close to being a constant 7.4 as possible. Thanks for any help anyone can offer me.
Hello, You LM317T needs. This IC is the adjustable voltage regulator that will handle 1 amp at 12 volts. It has three terminals. Note: Although the LM317T is facing you, the left terminal used to connect two 220 ohm resistors to the central terminal and 2.2k ohms to ground (negative). The central terminal is the power output (voltage regulated) and terminal right is the Power (B + line of the bike). When everything is connected, test the actual output voltage before using it. You will then need to select resistance which will give around 7.4 V, probably higher or lower than the original 2.2k ohms. LM317T need a heat sink. also need a capacitor filtering through the PO said, 1,000 UF 25V.
