AX6608B-600mA High PSRR,Low Noise LDO Regulator DataSheet

GENERAL DESCRIPTION
    The AX6608B is a low dropout, high PSRR, low noise linear regulator with very low quiescent. It can supply 600mA output current with low dropout voltage and very low output voltage. The Device includes pass element, error amplifier, band gap, current-limit and thermal shutdown circuitry. The characteristics of low dropout voltage and less quiescent current make it good for some critical current application, for example, some battery powered devices. The typical quiescent current is approximately 30μA. In the shutdown mode, the maximum supply current is less than 1uA. Due to internal flexible design, result in extensively fixed output voltage versions is 1.0V/1.2V/1.5V/1.8V/2.5V/2.8V/3.0V/3.3V. Built-in current-limit and thermal-shutdown functions prevent any fault condition from IC damage.
