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.
