Description

General part information

LT3093 Series

The LT3093 is a high performance low dropout negative linear regulator featuring ADI’s ultralow noise and ultrahigh PSRR architecture for powering noise sensitive applications. The device can be easily paralleled to further reduce noise, increase output current and spread heat on a PCB.The LT3093 supplies 200mA at a typical 190mV dropout voltage. Operating quiescent current is nominally 2.35mA and drops to 3µA in shutdown. The device’s wide output voltage range (0V to –19.5V) error amplifier operates in unity-gain and provides virtually constant output noise, PSRR, bandwidth, and load regulation independent of the programmed output voltage. Additional features are a bipolar enable pin, programmable current limit, fast startup capability and programmable power good to indicate output voltage regulation. The regulator incorporates a tracking function to control an upstream supply to maintain a constant voltage across the LT3093 to minimize power dissipation and optimize PSRR.The LT3093 is stable with a minimum 4.7µF ceramic output capacitor. Built-in protection includes internal current limit with foldback and thermal limit with hysteresis. The LT3093 is available in thermally enhanced 12-Lead MSOP and 3mm × 3mm DFN Packages.ApplicationsRF and Precision Power SuppliesVery Low Noise InstrumentationHigh Speed/High Precision Data ConvertersMedical Applications: Diagnostics and ImagingPost-Regulator for Switching Supplies
