It is stable with ceramic and high quality tantalum  
capacitor. The ultra low drop-voltage, low  
quiescent current and low noise makes it suitable  
for low power applications and in battery powered  
systems. Regulator ground current increases only  
slightly in dropout, further prolonging the battery  
life. Shutdown Logic Control function is available,  
this means that when the device is used as local  
regulator, it is possible to put a part of the board in  
standby, decreasing the total power consumption.  
Typical applications are in mobile phone and  
similar battery powered wireless systems,  
portable information appliances.
