RT9188 Datasheet | Richiek

Preliminary Dual, Ultra-Low Quiescent, 100m A 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 100m A 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. Key Features include current limit, thermal shutdown, faster transient response, ultra-low quiescent current (typically 8µA), low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the SOT-23-5 package, the RT9188 also offers a range of 1.2V to 5V with 0.1V per step.
