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)

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 or Tantalum Capacitors

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.
