The TPS7A3001 is a negative, high-voltage (–36V), ultralow-noise (15.1µVRMS, 72dB PSRR) linear regulator capable of sourcing a maximum load of 200mA.
●These linear regulators include 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 TPS7A3001 is designed using bipolar technology, and is ideal for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance. This design makes it an excellent choice to power operational amplifiers, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other high-performance analog circuitry.
●In addition, the TPS7A3001 of linear regulators is suitable for post dc/dc converter regulation. By filtering out the output voltage ripple inherent to dc/dc switching conversion, maximum system performance is provided in sensitive instrumentation, test and measurement, audio, and RF applications.
●For applications where positive and negative high-performance rails are required, consider TI’s TPS7A49xx family of positive high-voltage, ultralow-noise linear regulators.
