Description

General part information

LT3029 Series

The LT3029 is a dual, micropower, low noise, low dropout linear regulator. The device operates either with a common input supply or independent input supplies for each channel, over an input voltage range of 1.8V to 20V. Each output supplies up to 500mA of output current with a typical dropout voltage of 300mV. Quiescent current is well controlled in dropout. With an external 10nF bypass capacitor, output noise is only 20μVRMSover a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 55μA quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 1μA. Shutdown control is independent for each channel, allowing for flexible power management.The LT3029 optimizes stability and transient response with low ESR ceramic output capacitors, requiring a minimum of only 3.3μF. The regulator does not require the addition of ESR, as is common with other regulators.Internal circuitry provides reverse-battery protection, reverse-current protection, current limiting with foldback and thermal shutdown. The device is available as an adjustable output voltage device with a 1.215V reference voltage. The LT3029 is offered in the thermally enhanced 16-lead MSOP and 16-lead, low profile (4mm × 3mm × 0.75mm) DFN packages.ApplicationsGeneral Purpose Linear RegulatorBattery-Powered SystemsMicroprocessor Core/Logic SuppliesPost Regulator for Switching SuppliesTracking/Sequencing Power Supplies
