RT9170 Datasheet | Richtek

.. 300m A, 15μA Quiescent Current CMOS LDO Regulator General Description The RT9170 is CMOS ultra low quiescent current and low dropout (ULDO) regulators. The devices are capable of supplying 300m A of output current continuously. The RT9170's performance is optimized for batterypowered systems to deliver 15μA 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.
