The TPS723-Q1 low-dropout (LDO) negative voltage regulator offers an ideal combination of features to support low noise analog and mixed-signal applications. The TPS723 supports input voltages from –10V to –2.7V, and outputs from –10V to –1.186V (in adjustable configuration). This regulator is stable with small, low-cost ceramic capacitors (up-to 2.2µF), and includes enable (EN) and noise reduction (NR) functions.

The TPS723Q1 supports very tight DC accuracy of ±1.6% (new chip) over line, load and temperature range. The device responds quickly to line and load transients. The TPS723Q1 supports a low dropout of typically 140mV (typical, new chip) at 200mA of load current. The device has built-in protection mechanism for over-current and overtemperature for reliable operation of the LDO.

The TPS723Q1 supports low noise on output (60µVRMS with NR cap of 10nF) and available in a small 5-pin SOT-23 package, with performance fully specified over a temperature range of –40°C to +125°C.
