The TPS7A30 series of devices are negative, high-voltage (–35 V), ultralow-noise (15.1 µVRMS, 72-dB PSRR) linear regulators that can source a maximum load of 200 mA.

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 include built-in current limit and thermal shutdown protection to safeguard the device and system during fault conditions.

The TPS7A30 family 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 the device 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 TPS7A30 family 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 that require positive and negative high-performance rails, consider TI’s TPS7A49 family of positive high-voltage, ultralow-noise linear regulators.
