HIGH POWER WHITE LED DRIVER
300mA ULTRA-LOW NOISE, ULTRA-FAST
DESCRIPTION
FEATURES
The A8113 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The A8113 performance is optimized
for battery-powered systems to deliver ultra low noise
and low quiescent current. A noise bypass pin is
available for further reduction of output noise.
Regulator ground current increases only slightly in
dropout, further prolonging the battery life. The A8113
also works with low-ESR ceramic capacitors, reducing
the amount of board space necessary for power
applications, critical in hand-held wireless devices.
The A8113 consumes less than 0.01μA in shutdown
mode and has fast turn-on time less than 50μs. The
other features include ultra low dropout voltage, high
output accuracy, current limiting protection, and high
