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.

Reverse Battery Protection  
Output voltage range is from 1.21V to 20V. The LT1963A  
regulators are stable with output capacitors as low as  
10µF. Internal protection circuitry includes reverse bat-  
tery protection, current limiting, thermal limiting and  
reverse current protection. The devices are available in  
fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V and as  
an adjustable device with a 1.21V reference voltage. The  
LT1963A regulators are available in 5-lead TO-220, DD,  
3-lead SOT-223, 8-lead SO and 16-lead TSSOP packages.
