AX6642A

AX6642/A 1.5A High Output Current LDO Regulator  GENERAL DESCRIPTION The AX6642/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 1.5A. 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 50µA. 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.  FEATURES Input voltage range : 2.6V~5.5V Dropout voltage is 450mV at 1.5A output current @ VOUT = 3.30V Guaranteed 1.5A output current Low quiescent current is 50µA (typ.) Fixed Output voltage is form 1.2 V to 5V by 0.1V steps.
