LT1963A Series  
1.5A, Low Noise,  
Fast Transient Response  
LDO Regulators  
FEATURES  
DESCRIPTION  
TheLT®1963Aseriesarelowdropoutregulatorsoptimized  
for fast transient response. The devices are capable of  
supplying 1.5A of output current with a dropout voltage of  
340mV. Operating quiescent current is 1mA, dropping to  
<1μA in shutdown. Quiescent current is well controlled; it  
does not rise in dropout as it does with many other regula-  
tors. In addition to fast transient response, the LT1963A  
regulators have very low output noise which makes them  
ideal for sensitive RF supply applications.
