The LT ? 3023 is a dual, micropower, low noise, low drop-
out regulator. With an external 0.01μF bypass capacitor,
output noise drops to 20μV RMS 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 ?exibility 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 LT3023 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, thermal limiting and reverse
current protection. The device is available as an adjust-
able device with a 1.22V reference voltage. The LT3023
regulator is available in the thermally enhanced 10-lead
MSOP and DFN packages.
