Product Overview

The LM323KSTEEL is a 3A 5V Positive Regulator, new circuit design and processing techniques are used to provide the high output current without sacrificing the regulation characteristics of lower current devices, offers improved precision over the standard LM323. Parameters with tightened specifications include output voltage tolerance, line regulation and load regulation. The 3A regulator is virtually blowout proof. Current limiting, power limiting and thermal shutdown provide the same high level of reliability obtained with these techniques in the 1A regulator. No external components are required for operation of the regulator. If the device is more than 4 inches from the filter capacitor, however, a 1µF solid tantalum capacitor should be used on the input. A 0.1µF or larger capacitor may be used on the output to reduce load transient spikes created by fast switching digital logic or to swamp out stray load capacitance.
  • Guaranteed 1% initial accuracy
  • Internal current and thermal limiting
  • 0.01Ω Typical output impedance
  • 30W Power dissipation
  • P+ Product enhancement tested


Power Management


This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
