DESCRIPTION
●The LT®3023 is a dual, micropower, low noise, low drop out regulator. With an external 0.01μF bypass capacitor, output noise drops to 20μVRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 20μA quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 0.1μA. Shutdown control is independent for each channel, allowing for flexibility in power management. The device is capable of operating over an input voltage from 1.8V to 20V, and can supply 100mA of output current from each channel with a dropout voltage of 300mV. Quiescent current is well controlled in dropout.
