Description for the TPS723
The TPS723 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 config). This regulator is stable with small, low-cost ceramic capacitors (up-to 2.2µF), and includes enable (EN) and noise reduction (NR) functions.
The TPS723 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 TPS723 supports a low dropout of typically 140mV (typ , 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 TPS723 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.
