UNISONIC TECHNOLOGIES CO., LTD LR1198 300mA, ULTRA-LOW NOISE, ULTRA-FAST CMOS LDO REGULATOR CMOS IC  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.
