LT323AT#PBF

LT323AT#PBF is an improved version of the popular LM123/LM323 5V, 3Amp regulator. This new device offers maximum initial output voltage tolerance of 1% and maintain a maximum tolerance 3% over worst case operating conditions. Line and load regulation is also improved by a factor 2. This tightened specification ease design and application problems since safety margin is improved. Also, error budgets in other parts of the system can be expanded, and output voltages at the end of long supply runs can be more accurately maintained. It incorporates linear technology advanced design, process and test techniques for improved quality and reliability over similar device types. Specifically, all device is burned in by shorting the output, thereby forcing the regulator into its current limit and eventually, thermal limit. The ensures that all device protection feature is functional. Application includes local 5V regulators, on card regulators, lab supplies, instrumentation supplies.
