DESCRIPTION The TPS72325-Q1 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, and support outputs from –10V to –1.2V. 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 (65dB at 1kHz) and low noise (60mVRMS) make the TPS72325-Q1 ideal for low-noise applications. The TPS72325-Q1 uses a precision voltage reference to achieve 2% overall accuracy over load, line, and temperature variations. Available in a small SOT23-5 package, the TPS72325-Q1 is fully specified over a temperature range of –40°C to +125°C.
