FEATURES  
DESCRIPTION  
The LT®1521/LT1521-3/LT1521-3.3/LT1521-5 are low  
dropout regulators with micropower quiescent current  
and shutdown. These devices are capable of supplying  
300mA of output current with a dropout voltage of 0.5V.  
Designed for use in battery-powered systems, the low  
quiescent current, 12µA operating and 6µA in  
shutdown, makes them an ideal choice. The quiescent  
current is well controlled; it does not rise in dropout as it  
does with many other low dropout PNP regulators.

Other features of the LT1521/LT1521-3/LT1521-3.3/  
LT1521-5 include the ability to operate with very small  
output capacitors. They are stable with only 1.5µF on the  
outputwhilemostolderdevicesrequirebetween10µFand  
100µF for stability. Small ceramic capacitors can be used,  
enhancing manufacturability. Also, the input may be con-  
nectedtovoltageslowerthantheoutputvoltage,including  
negative voltages, without reverse current flow from out-  
puttoinput.ThismakestheLT1521seriesidealforbackup  
power situations where the output is held high and the  
input is low or reversed. Under these conditions only 5µA  
will flow from the output pin to ground.
