The RT9170 is CMOS ultra low quiescent current and low dropout (ULDO) regulators. The devices are capable of supplying 300mA of output current continuously.
The RT9170's performance is optimized for battery- powered systems to deliver 15uA ultra low quiescent current and extremely low dropout voltage. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.
The devices are available in fixed output voltages range of 1.2V to 3.3V with 0.1V per step. The RT9170 regulators are available in SOT-23-3, SOT-23-5 and 3-lead SOT-89 packages.
