RT9188

Pinout




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 battery-powered 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 8uA), 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.
