LM323 Linear Voltage Regulators, Texas Instruments


The LM323 positive voltage regulator by Texas Instruments is a three-terminal device with a pre-set 5 V output for a 3 Amp current output. The technique that is used in this circuit means that the high output current is still provided without it being sacrificed. The fixed linear voltage regulator is a durable device that incorporates current limiting, power limiting and thermal shutdown.
