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 ...
The circuit was designed to provide an adjustment with a power supply that is symmetrically designed while providing a voltage range of 1.25V to 30V at 1A current. LM317 – an adjustable 3-terminal ...
Many electronics circuits begin operation at voltages below 1.25 V. But popular adjustable regulators such as the LM317, LM350, and LM338 can provide output voltages only above 1.25 V, and the L200 ...
