This document introduces the features and characteristics of the LT3029 product. The LT3029 is a monolithic LDO that integrates two independent 500mA regulators. It has a wide input voltage range of 1.8V to 20V and a dropout voltage of 300mV at full load. The output voltage can be adjusted to 1.215V reference voltage. With an external bypass capacitor, the output voltage noise is less than 20µVRMS. Each channel requires a minimum of 3.3µF ceramic output capacitor to be stable. The quiescent current is 55µA per channel and drops below 1µA in shutdown. Reverse-battery protection, reverse-current protection, current limit fold-back and thermal shutdown are all integrated into the package, making it ideal for battery-powered systems.
The document describes the LT3029, which integrates two independent 500mA LDOs. It features a wide input voltage range from 1.8V to 20V and includes reverse-battery protection, current limit foldback, and thermal shutdown. The device is available in 16-lead MSOP or 4mm x 3mm DFN packages.
The output voltage can be adjusted down to 1.215V.
A minimum of 3.3uF ceramic output capacitor is needed for each channel.
The device comes in a 4mm x 3mm x 0.75mm DFN package.
