AX6643-1.5A High Output Current LDO Regulator DataSheet 停产

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~5.5V
- 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.)
- Maximum supply current in shutdown mode < 2uA
- Fast transient response
- Current limit and thermal shutdown protection
- Short circuit current fold-back
- Available in the SOP-8L, TO252-5L and TDFN-6L Pb-Free Packages
