The AX6603A is a 300mA, low quiescent, high PSRR, low noise and low dropout linear regulator. 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 90μA. In the shutdown mode, the maximum supply current is less than 0.1uA. Built-in current-limit, Short current protection and thermal-shutdown functions prevent any fault condition from IC damage.
