TI TPS72301DBVTG4

The TPS723 low-dropout (LDO) negative voltage regulator offers an ideal combination of features to support low noise applications. This device is capable of operating with input voltages from -10 V to -2.7 V, and support outputs from -10 V to –1.2 V. This regulator is stable with small, low-cost ceramic capacitors, and include enable (EN) and noise reduction (NR) functions. Thermal short-circuit and over-current protections are provided by internal detection and shutdown logic. High PSRR (65 dB at 1 kHz) and low noise (60 μV_RMS) make the TPS723 ideal for low-noise applications. The TPS723 uses a precision voltage reference to achieve 2% overall accuracy over load, line, and temperature variations. Available in a small SOT23-5 package, the TPS723 is fully specified over a temperature range of -40°C to 125°C.
