Product Summary

The TPS7A3001DGNR is a negative, high-voltage (-36V), ultralow-noise (15.1mVRMS, 72dB PSRR) 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 TPS7A3001DGNR include Supply Rails for Op Amps, DACs, ADCs, and Other High-Precision Analog Circuitry, Audio, Post DC/DC Converter Regulation and Ripple filtering, Test and Measurement, RX, TX, and PA Circuitry, Industrial Instrumention, Base Stations and Telecom Infrastrucure, –12V and –24V Industrial Buses.
