The TPS72301DBVTG4 is a Negative Output Low-dropout Linear Regulator that 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, low-cost 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 TPS72301 ideal for low-noise applications. It uses a precision voltage reference to achieve 2% overall accuracy over load, line and temperature variations. The TPS72301 has internal circuitry that monitors and limits output current to protect the regulator from damage under all load conditions. When output current reaches the output current limit, protection circuitry turns on, reducing output voltage to ensure that current does not increase.
