Description

General part information

LT1965 Series

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 500μA for the adjustable version, reducing to <1μA 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.Output voltage ranges from 1.20V to 19.5V. The LT1965 regulators are 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 series are available in fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V, and as an adjustable device with a 1.20V reference voltage. The package offerings include the 5-lead TO-220, 5-lead DD-Pak as well as the thermally enhanced 8-lead MSOP and low profile (0.75mm) 8-lead 3mm × 3mm DFN.ApplicationsLogic Power SuppliesPost Regulator for Switching SuppliesLow Noise Instrumentation
