AX6646/A
300mA LDO Regulator with Enable
GENERAL DESCRIPTION
The AX6646/A is a 300mA, low quiescent, high PSRR, low noise and low dropout
linear regulator. The Device includes pass element, error amplifier, band-gap, current limit
and thermal shutdown circuitry. 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 40µA. In the
shutdown mode, the maximum supply current is less than 1uA. The Output voltage is
adjustable from 0.8V to 5.5V. Built-in current-limit, Short current protection and
thermal-shutdown functions prevent any fault condition from IC damage.
