The LT3023 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 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.

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 adjustable device with a 1.22V reference voltage. The LT3023 regulator is available in the thermally enhanced 10-lead MSOP and DFN packages.

Product Detail

Demonstration circuit 704 is a dual output regulator based on the LT3023 IC, which consists of two identical 100mA LDO linear regulators. The DC704 has an input voltage range of 2.3V to 20V and the output is jumper-selectable, with output voltage values of 2.5V, 3.3V, 5V or a user-determined value. The DC supply current is typically only 20uA (per channel) at no load. The LT3023 comes in a small 10-pin DFN package, which has an exposed pad on the bottom-side of the IC for better thermal performance.
