The LT1121/LT1121-3.3/LT1121-5 are micropower low  
dropout regulators with shutdown. These devices are  
capable of supplying 150mA of output current with a  
dropout voltage of 0.4V. Designed for use in battery-  
powered systems, the low quiescent current, 30µA oper-  
ating and 16µA 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.

Thermal Limiting  
Other features of the LT1121/LT1121-3.3/LT1121-5 in-  
clude the ability to operate with very small output capaci-  
tors. They are stable with only 0.33µF on the output while  
most older devices require between 1µF and 100µF for  
stability. Small ceramic capacitors can be used, enhanc-  
ing manufacturability. Also the input may be connected to  
ground or a reverse voltage without reverse current flow  
from output to input. This makes the LT1121 series ideal  
for backup power situations where the output is held high  
and the input is at ground or reversed. Under these  
conditions only 16µA will flow from the output pin to  
ground.
