Low Noise Rail-to-Rail Negative Regulator with Programmable Current Limit

August 01, 2014 // By Electronics EETimes

The LT®3090 is a low noise single resistor programmable negative regulator based upon current reference architecture. The advantage of this architecture is that output voltage is rail-to-rail programmable while always maintaining unity gain operation. Hence, the bandwidth/transient response, noise, PSRR and load regulation are all independent of output voltage.
