Analog Devices Inc. LT1965 Low Dropout Linear Regulators
Analog Devices LT1965 Low Dropout Linear Regulators supply 1.1A of output current with a 310mV typical dropout voltage. The devices feature an operating quiescent current of 500µA for the adjustable version, reducing to <1µA in shutdown. Quiescent current is well controlled and doesn't rise in dropout like other regulators. The LT1965 regulators' very low output noise makes them ideal for sensitive RF and DSP supply applications.
