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.

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,
