Preliminary
RT9188
Dual, Ultra-Low Quiescent, 100mA CMOS LDO Regulator
General Description
The RT9188 series are an efficient, precise dual-channel CMOS LDO regulator optimized for ultra-low-quiescent applications. Both regulator outputs are capable of sourcing 100mA of output current.
The RT9188's performance is optimized for batterypowered systems to deliver extremely low dropout voltage and ultra-low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The RT9188 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.
