GENERAL DESCRIPTION
Internally Compensated internal Soft Start makes AMS4122 one of the simplest and easiest switching regulators to use with the minimum external components. Since both devices share one single package the thermal protection turns off both devices when the die temperature exceeds approximately 135°C. Both regulators are adjustable using a 0.600V reference for low output voltage settings.
