TPS72301DBVR

Product Summary

The TPS72301DBVR low-dropout (LDO) negative voltage regulator offers an ideal combination of features to support low noise applications. The device is capable of operating with input voltages from -10 V to -2.7 V, and supporting outputs from -10 V to -1.2 V. The regulator is stable with small, low-cost ceramic capacitors, and include enable (EN) and noise reduction (NR) functions. Thermal short-circuit and over-current protection is provided by internal detection and shutdown logic. High PSRR (65 dB at 1 k Hz) and low noise (60 μVRMS) make the TPS72301DBVR ideal for low-noise applications. The TPS72301DBVR uses a precision voltage reference to achieve 2% overall accuracy over load, line, and temperature variations. Available in a small SOT23.5 package, the TPS72301DBVR is fully specified over a temperature range of -40℃ to 125℃. The applications of the TPS72301DBVR are: Optical Drives; Optical Networking; Noise Sensitive Circuitry; GaAs FET Gate Bias; Video Amplifiers.
