LR1198
CMOS IC
300mA, ULTRA-LOW NOISE,
ULTRA-FAST CMOS LDO
REGULATOR
DESCRIPTION
The LR1198 low-noise, low-dropout, linear regulator operates
from a 2.5V to 5.5V input and is guaranteed to deliver 300mA.
The LR1198 is designed and optimized for battery-powered
systems to work with low noise and low quiescent current. For
further reduction of output noise, a noise bypass pin is available.
The LR1198 also requires only 1μF (typ.) of output
capacitance for stability with any load, reducing the amount of
board space necessary for power applications, critical in
hand-held wireless devices.
The LR1198 consumes less than 0.01μA in shutdown mode.
The other features include ultra low dropout voltage, current
limiting protection, thermal shutdown protection and high ripple
rejection ratio.
FEATURES
* 300mA Guaranteed Output Current
