Overview
AX6608A 300mA Low Dropout Linear Regulator  GENERAL DESCRIPTION The AX6608A is a low dropout, high PSRR, low noise linear regulator with very low quiescent.
It can supply 300mA output current with low dropout about 250mV.
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 30µA.
Built-in current-limit and thermal-shutdown functions prevent any fault condition from IC damage.
The AX6608A series are offering three different fixed output voltage types including 1.
0V, 1.
2V, 1.
5V, 1.
8V, 2.
5V, 2.

The input capacitor in VIN the range of 1uF to 10uF is sufficient.
GND Ground Output Voltage, The AX6608A is stable with an output capacitor 1uF for greater.
The larger output capacitor will be required for VOUT application with large transit load to limit peak voltage transits, besides could reduce output noise, improve stability, PSRR.
