Product Summary

The LT1963AES8 is a low dropout regulator opti-mized for fast transient response. The devices are capable of supplying 1.5A of output current with a dropout voltage of 340mV. Operating quiescent current is 1mA, dropping to < 1mA in shutdown. Quiescent current is well controlled; it does not rise in dropout as it does with many other regulators. In addition to fast transient response, the LT1963AES8 has very low output noise which makes them ideal for sensitive RF supply applications. The applications of the LT1963AES8 include 3.3V to 2.5V Logic Power Supplies; Post Regulator for Switching Supplies.
