LT1965 Series

1.1A, Low Noise,

Low Dropout Linear Regulator

FEATURES

DESCRIPTION

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 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.
