The LT®1965 series are low noise, low dropout linear regu-
lators. 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 limit-
ing 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.
