LT1965 Series

1.1A, Low Noise,

Low Dropout Linear Regulator

FEATURES

DESCRIPTION

TheLT^®1965seriesarelownoise, lowdropoutlinearregu-

lators. The devices supply 1.1A of output current with a

310mVtypicaldropoutvoltage.Operatingquiescentcurrent

is 500μA for the adjustable version, reducing to <1μA in

shutdown. Quiescentcurrentiswellcontrolled;itdoesnot

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 Current: 1.1A

Dropout Voltage: 310mV

Low Noise: 40μV

(10Hz to 100kHz)

RMS

500μA Quiescent Current (Adjustable Version)

Wide Input Voltage Range: 1.8V to 20V

No Protection Diodes Needed

Controlled Quiescent Current in Dropout

Adjustable Output from 1.20V to 19.5V

Fixed Output Voltages: 1.5V, 1.8V, 2.5V, 3.3V

< 1μA Quiescent Current in Shutdown

Stable with 10μF Output Capacitor

Stable with Ceramic, Tantalum or Aluminum

Electrolytic Capacitors

Reverse Battery Protection

No Reverse Current

Current Limit with Foldback Protection

Thermal Limiting

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, currentlimitingwithfoldback, thermallimiting

and reverse current protection. The LT1965 series are

available in ﬁxed output voltages of 1.5V, 1.8V, 2.5V, 3.3V,

andasanadjustabledevicewitha1.20Vreferencevoltage.

The package offerings include the 5-lead TO-220, 5-lead

DD-PAK as well as the thermally enhanced 8-lead MSOP

5-Lead TO-220, DD-PAK, Thermally Enhanced 8-Lead

MSOP and 8-Lead 3mm × 3mm DFN Packages

and low-proﬁle (0.75mm) 8-lead 3mm × 3mm DFN.
