Toshiba has implemented a lot of great technology into their LDOs, which allows them to achieve key advantages like high accuracy, low noise, and fast transient response for sensitive systems. This is complemented by having low dropout, low load regulation, and low quiescent current. Typically speaking, advantages from both areas are tradeoffs in the sense that in order to be good in one area, there must be sacrifices in the other. Toshiba has managed to achieve both, which is one of the many reasons why these LDOs are exceptional.
