Product Details

The LT?1965 is a low noise, low dropout linear regulator. The device delivers 1.1A of output current and a typical dropout voltage of 310mV. Operating quiescent current is 500µA (adjustable version) and drops below 1µA in shutdown mode. Quiescent current is well controlled; unlike with many other regulators, it does not rise under dropout conditions. The LT1965 regulator has very low output noise, making it ideal for sensitive RF and DSP power supply applications.

The output voltage can vary from 1.20V to 19.5V. The LT1965 regulator is stable with output capacitors as low as 10µF. Internal protection circuits include reverse battery protection, current limit with foldback protection, thermal limit, and reverse current protection. The LT1965 family is available in fixed output voltages of 1.5V, 1.8V, 2.5V and 3.3V, as well as with a 1.20V reference as an adjustable device. Packages available include 5-lead TO-220, 5-lead DD-PAK, and thermally enhanced 8-lead MSOP and low profile (0.75mm) 8-lead 3mm x 3mm DFN packages.
