3 Description

The TPS723xx family of low-dropout (LDO) negative voltage regulators offers an ideal combination of features to support low noise applications. These devices are capable of operating with input voltages from –10 V to –2.7 V, and support outputs from –10 V to –1.2 V. These regulators 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 kHz) and low noise (60 μVRMS) make the TPS723xx ideal for low-noise applications.

The TPS723xx 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.
