TPS7A3301RGWR

The TPS7A33 series of linear regulators are negative voltage (-36 V), ultralow-noise (16-μVRMS, 72-dB PSRR) linear regulators capable of sourcing a maximum load of 1 A. The TPS7A33 series include a complementary metal oxide 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 shutdown features to protect the device and system during fault conditions. The TPS7A33 family is designed using bipolar technology primarily for high-accuracy, high-precision instrumentation 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 highperformance 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 DCDC switching conversion, maximum system performance is ensured in sensitive instrumentation, medical, test and measurement, audio, and RF applications.
