NCP170
The NCP170 series of CMOS low dropout regulators are designed
specifically for portable battery-powered applications which require
ultra-low quiescent current. The ultra-low consumption of typ. 500 nA
ensures long battery life and dynamic transient boost feature improves
device transient response for wireless communication applications.
The device is available in small 1
×
1 mm XDFN4, SOT-563 and
TSOP-5 packages.
