TPS72325DBVTG4 Description

The TPS72325DBVTG4 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 includes enables (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 μVRMS) make the TPS723 ideal for low-noise applications.
