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

The LT®3090 is a low-noise negative voltage regulator programmable with a single resistor based on a current reference architecture. The advantage of this architecture is programmable rail-to-rail output voltage while always maintaining unity gain operation. Therefore, bandwidth/transient response, noise, PSRR, and load regulation are not affected by the output voltage.

In addition, the LT3090 features programmable current limit, positive or negative current monitoring, programmable cable drop compensation and bidirectional shutdown, and can be easily paralleled for higher current operation or to spread heat on surface mount circuit boards . The LT3090's low noise and rich features make it ideal for a variety of applications.
