1. Describe

The TPS7A3301RGWR family of linear regulators are negative voltage (–36 V), ultralow noise (16-μVRMS, 72-dB PSRR) linear regulators capable of supplying 1 A maximum load. The TPS7A33 family includes a complementary metal oxide semiconductor (CMOS) logic level compatible enable pin (EN) to allow user-customizable power management schemes. Other available features include built-in current limit and thermal shutdown to protect equipment and systems during fault conditions. Designed with bipolar technology, the TPS7A3301RGWR family is primarily intended for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance. This feature makes it ideal for op amps, analog-to-digital converters (ADCs), Digital-to-Analog Converters (DACs) and other high-performance analog circuits. In addition, the TPS7A3301RGWR series linear regulators are suitable for post-DC-DC converter regulation. go through Filters out the output voltage ripple inherent in DC-DC switching conversions, ensuring maximum system performance in sensitive instrumentation, medical, test and measurement, audio and RF applications. For positive and negative high applications If performance rails are required, consider the TPS7A4700 positive high voltage, ultralow noise, low dropout linear regulator.
