AXElite AX6643
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.

GENERAL DESCRIPTION
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~5.5V Adjustable Output voltage form 0.8V to 5.0V Dropout voltage is 450mV at 1.5A output current @ VOUT = 3.30V Guaranteed 1.5A output current Low quiescent current is 50µA (typ.)
