Product Summary

The TPS7A3401DGNR is a negative, high-voltage (-20V), ultralow-noise linear regulator capable of sourcing a maximum load of 200mA. The linear regulator includes a CMOS logic-level-compatible enable pin and capacitor-programmable soft-start function that allows for customized power-management schemes. Other features available include built-in current limit and thermal shutdown protection to safeguard the device and system during fault conditions. The applications of the TPS7A3401DGNR include Cost-Effective Supply Rails for Op Amps, DACs, ADCs, and Other High-Precision Analog Circuitry, Cost-Effective Post DC/DC Converter Regulation and Ripple Filtering.
