LT3093EMSE#PBF

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. Additional features are a bipolar enable pin, programmable current limit, fast start-up 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 device to minimize power dissipation and optimize PSRR. It is stable with a minimum 4.7µF ceramic output capacitor. It is widely used in application such as RF and precision power supplies, very low noise instrumentation, high speed/high precision data converters, medical applications: diagnostics and imaging, post-regulator for switching supplies etc.
