The LT3023EDD is a high-performance dual low dropout regulator (LDO) from Linear Technology, designed to deliver a continuous dual 100mA output. It is housed in a compact DFN package, making it ideal for space-constrained applications. The LT3023 is characterized by its low noise output, high power supply rejection ratio (PSRR), and low quiescent current, distinguishing it as an excellent choice for sensitive RF and analog circuitry that require a clean and stable power supply.

Each of the two independent LDOs has a low dropout voltage of merely 300mV at full load, which allows for efficient operation even when the input-to-output differential is minimal. This feature is particularly beneficial in battery-operated devices, where maximizing the usage of available voltage is crucial. The LT3023EDD operates with a wide input voltage range from 1.8V to 20V, granting flexibility in various supply environments.

The device boasts an impressive low output noise of only 20µVRMS across a 10Hz to 100kHz bandwidth, and a PSRR of 60dB at 1kHz, which ensures a clean voltage supply free from the common fluctuations found in input power sources. Additionally, the LT3023's quiescent current is exceptionally low, at only 50µA per regulator, which significantly enhances battery life in portable applications.

Each regulator's output voltage is adjustable from 1.22V to 20V and can be set with external resistors. The LT3023EDD also features a shutdown mode, reducing the quiescent current to less than 1µA and providing an additional power conservation mode for battery-powered devices.

Protection features of the LT3023EDD include over-temperature protection and short-circuit protection, ensuring reliable operation under adverse conditions. The device's thermal performance is also optimized with its DFN package, which provides efficient heat dissipation.

With its combination of low noise, high PSRR, low quiescent current, and wide input voltage range, the LT3023EDD is an excellent choice for powering precision analog circuits, portable instrumentation, and wireless devices where performance and battery life are paramount.
