LT1965 1.1A, Low Noise, Low Dropout Linear Regulator FEATURES ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ DESCRIPTION The LT1965 is a low noise, low dropout linear regulator. The device supplies 1.1A of output current with a 290mV typical dropout voltage. Operating quiescent current is 500μA, reducing to <1μA in shutdown. Quiescent current is well controlled; it does not rise in dropout as with many other regulators. The LT1965 regulator has very low output noise which makes it ideal for sensitive RF and DSP supply applications. Output voltage ranges from 1.20V to 19.5V. The LT1965 regulator is stable with output capacitors as low as 10μF. Internal protection circuitry includes reverse battery protection, current limiting with foldback, thermal limiting and reverse current protection. The LT1965 is available as an adjustable device with a 1.20V reference voltage. The package offering includes the 5-lead TO-220, 5-lead DD-PAK as well as the thermally enhanced 8-lead MSOP and 8-lead 3mm × 3mm DFN. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
