The two power supply circuits are presented to illustrate the soft start procedure using LM317 and L200 integrated circuits where each reaches the desired output of 15 V gradually for a period of 5 ...

Every project needs a power supply. As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. We’ve found four different ...

This is an LM317 based adjustable voltage regulator with a maximum output of 3V and 1.5A. The output voltage depends on the VIN, R1 and R2 values, so the circuit can be modified to use with a maximum ...
