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)

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

Output voltage ranges from 1.20V to 19.5V. The LT1965

regulators are stable with output capacitors as low as

10µF.Internalprotectioncircuitryincludesreverse-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

MSOPandlowprofile(0.75mm)8-lead3mm× 3mmDFN.
