4.1.
The internal compensation is optimized for a 44uF output capacitor and a 4.7uH inductor. The minimum allowable
value for the output capacitor is 33uF. To keep the output ripple low, a low ESR (less than 35mOhm) ceramic is
recommended. The inductor range is 4.7uH +/-20%. For optimal over-current protection, the inductor should be
able to handle up to the regulator current limit without saturation.
