AX6643 1.5A High Output Current LDO Regulator  GENERAL DESCRIPTION The AX6643 is a low noise, high output current, low quiescent current and low dropout linear regulator. The Device includes pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry. The output current is up to 1.5A, the characteristics of low dropout voltage and less quiescent current make it good for some critical current application, and for example, some battery powered devices. The typical quiescent current is approximately 50µA. In the shutdown mode, the maximum supply current is less than 2uA. Built-in current-limit, Short current protection and thermal-shutdown functions prevent any fault condition from IC damage.  FEATURES Input voltage range : 2.6V~5.
