DescripTion  
The LTC®3025-X is a micropower, VLDO™ (very low drop-  
out)linearregulatorwhichoperatesfrominputvoltagesas  
low as 0.9V. The device is capable of supplying 500mA of  
outputcurrentwithatypicaldropoutvoltageofonly85mV.  
A BIAS supply is required to run the internal reference and  
LDOcircuitrywhileoutputcurrentcomesdirectlyfromthe  
IN supply for high efficiency regulation. The LTC3025-1  
features an adjustable output with a low 0.4V reference  
while the LTC3025-2, LTC3025-3, and LTC3025-4 have  
fixed 1.2V, 1.5V and 1.8V output voltages respectively.

Fast Transient Recovery  
The LTC3025-X’s low quiescent current makes it an ideal  
choiceforuseinbattery-poweredsystems.For3-cellNiMH  
and single cell Li-Ion applications, the BIAS voltage can  
be supplied directly from the battery while the input can  
come from a high efficiency buck regulator, providing a  
high efficiency, low noise output.
