6.1 Overview

The TPS723 is a low-dropout, negative linear voltage regulator with an output tolerance of ±1.6% across load, and temperature variation (for the new chip) and a rated load current of 200mA. The device is offered in trimmed output voltages between –1.5V and –5.2V and as an adjustable regulator from –1.186V to –10V. The device features very low noise (60 μVRMS with NR cap of 10nF) and high power-supply rejection ratio (40dB typical at 100kHz) , making the TPS723 designed for high-sensitivity analog and RF applications. A shutdown mode is available, reducing ground current to 2-μA maximum over temperature and process.
