With an external 0.01μF bypass capacitor, output noise is a low 20μV RMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 25μA 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.The LT3027 regulator is stable with output capacitors as low as 1μF. Small ceramic capacitors can be used without the series resistance required by other regulators.Internal protection circuitry includes reverse battery protection, current limiting and thermal limiting protection. The device is available as an adjustable device with a 1.22V reference voltage. The LT3027 regulator is available in the thermally enhanced 10-lead MSOP and low profile (0.75mm) 3mm × 3mm DFN packages.Protected by U.S. Patents, including 6118263, 6144250.
