? GENERAL DESCRIPTION

The AX6634/A is a low noise, low quiescent current, low dropout and high output accuracy linear regulator. The Device includes pass element, error amplifier, band-gap, current-limit and thermal shutdown circuitry. The output current is up to 600mA. The characteristics of low dropout voltage and less quiescent current make it good for some critical current application, for example, some battery powered devices. Due to internal flexible design, result in extensively fixed output voltage versions form 1.2V to 5V per 0.1V steps. Built-in current-limit, Short current protection and thermal-shutdown functions prevent any fault condition from IC damage.
