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 100k Hz 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 100m A of output current from Output 2 with a dropout voltage of 300m V. Output 1 can supply 500m A of output current with a dropout voltage of 300m V. Quiescent current is well controlled in dropout. The LT3024 regulator is stable with output capacitors as low as 1µF for the 100m A output and 3.3µF for the 500m A output. Small ceramic capacitors can be used without the series resistance required by other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available as an adjustable device with...
