The AUX powered 6mA LDO provides a regulated rail for  
external microcontrollers and sensors while the main  
output is charging. In shutdown, I is reduced to 10µA  
and integrated thermal shutdown offers protection from  
overtemperature faults. The LTC3105 is offered in 10-lead  
3mm×3mm×0.75mmDFNand12-leadMSOPpackages.
