The LT ®3024 is a dual, micropower, low noise, low dropout 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 30µA quiescent current per output makes it an ideal choice. In shutdown, quiescent current drops to less than 0.1µA. Shutdown control is independent for each output, allowing for flexibility in power management. The device is capable of operating over an input voltage range of 1.8V to 20V. The device can supply 100mA of output current from Output 2 with a dropout voltage of 300mV. Output 1 can supply 500mA of out...
