DESCRIPTION
●The TPS723xx-Q1 family of 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 –10V to –2.7V. The TPS72325-Q1 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 1kHz) and low
●noise (60μVRMS) make the TPS723xx-Q1 ideal for low-noise applications.
