General Description
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 15
μA 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.
