The LT1965 series are low noise, low dropout linear regulators. The devices supply 1.1A of output current with a 310mV typical dropout voltage. Operating quiescent current is 500A for the adjustable version, reducing to <1A in shutdown. Quiescent current is well controlled; it does not rise in dropout as with many other regulators. The LT1965 regulators have very low output noise which makes them ideal for sensitive RF and DSP supply applications.
