lm317hv variable high current variable power supply


Posted on Feb 5, 2014

LM317HV adjustable regulator is capable of supplying in excess of 1. 5A over a 1. 2V to 57V output range. The design of these high current power supply is very easy, because the LM317HV require just few external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. An optional output

capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejections ratios which are difficult to achieve with standard 3-terminal regulators. As you can see in the circuit diagram, these electronic project power supply require three LM317 regulators, connected in parallel to provide a maximum output current up to 4 amperes at a variable output voltage from 4. 5 volt up to 25 volt.
