The LT323AT#PBF is a 5V 3A Voltage Regulator offers maximum initial output voltage tolerance of 1% and maintain a maximum tolerance of 3% over worst case operating conditions. Line and load regulation are also improved by a factor of 2. These tightened specifications ease design and application problems since safety margins are 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. The LT323A incorporates advanced design, process and test techniques for improved quality and reliability over similar device types. Specifically, the device is burned in by shorting the output, thereby forcing the regulator into its current limit and eventually, thermal limit. This ensures that the device protection features are functional.
