Better Accuracy from the LM317
One of the oldest voltage regulators still in production is the LM317, which was introduced back in 1971 by National Semiconductor. While the present-day implementations of the LM317 are likely to have a modified version of the original chip design, the characteristics, pin-out and physical dimensions continue to remain the same.
