2007-08-10 05:58:00 Calculate LM317 Resistor Values This calculator is used to find the value of the voltage adjustment resistor required to set the output of an LM317 to a specified level. Typically R1 is 220 ohms or 240 ohms, but it could be some other value such as 150 or 470 ohms. Select a value for R2 ... More About: Calculate
Feedback Regulated, Isolated 9V Supply By IC 4011
2007-08-09 20:14:00 This circuit is my variation on Charles? floating 9V supply. My design uses feedback regulation instead of a zener shunt regulator to stabilize the output against battery voltage and load variations. Replacing the shunt regulator with feedback control makes the supply more efficient for output loads of less than about 500ua. ... More About: Feedback , Isolate
