The TPS7A33 series of linear regulators are negative voltage(-36 V)， ultralow-noise (16-pVRMs， 72-dBPSRR) linear regulators capable of sourcing amaximum load of 1 A. The TPS7A33 series include a complementary metaloxide semiconductor (CMOS) logic-level-compatible enable pin (EN) to allow for user-customizable power management schemes. Other features available include built-in current limit and thermal shut down features to protect the device and system during fault conditions. The TPS7A33 family is designed using bipolar technology primarily for high-accuracy, high-precision in strumentation applications, where clean voltage rails are critical to maximize system performance. This feature makes it ideal to power operational amplifiers，analog-to-digital converters (ADCs). digital-to-analog converters (DACs),and other high-performance analog circuitry. In addition, the TPS7A33 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 ensured in sensitive instrumentation. medical, test and measurement, audio, and RF applications For applications where positive and negative high-performance rails are required,consider the TPS7A4700 positive high-voltage, ultralow-noise, low-dropout linear regulator as well.
