TPS72301DBVT

The TPS72301DBVT is a 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 to -2.7V and support outputs from -10 to -1.2V. This regulator is stable with small, ceramic capacitors and includes enable (EN) and noise reduction (NR) functions. Thermal short-circuit and over-current protections are provided by internal detection and shutdown logic. High PSRR (65dB at 1kHz) and low noise (60µVRMS) make the device ideal for low-noise applications. The device uses a precision voltage reference to achieve 2% overall accuracy over load, line and temperature variations. It also features very low noise and high power-supply rejection ratio (PSRR), making it ideal for high-sensitivity analog and RF applications. A shutdown mode is available, reducing ground current to 2µA maximum over temperature and process.
