AX6639/A-3A High Output Current LDO Regulator DataSheet

GENERAL DESCRIPTION
    The AX6639/A 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 3A. 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 200μA. There are 1.5V, 1.8V, 2.5V, 3.3V fixed output voltage and adjustable output versions (SOP-8L-EP and TO263 5L Only). Built-in current-limit, Short current protection and thermal-shutdown functions prevent any fault condition from IC damage.
