The TPS72325 low-dropout (LDO) negative voltage regulators offers an ideal combination of features to support low noise applications. The devices are capable of operating with input voltages from −10 V to −2.7 V, and supporting outputs from −10 V to −1.2 V. These regulators TPS72325 are 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 1 k Hz) and low noise (60 VRMS) make the TPS72325 ideal for low-noise applications.
The TPS72325 uses a precision voltage reference to achieve 2% overall accuracy over load, line, and temperature variations. Available in a small SOT23−5 package, the TPS723xx family is fully specified over a temperature range of −40°C to 125°C.
