+ mas9160 is a voltage regulator ic with two low dropout voltage regulators, which both have their own enable/disable pin allowing the regulators to be turned off or on separately by pulling the particular control to low or high. due to the low noise level of only 30 vrms, mas9160 is suitable for sensitive circuits, e.g., in portable applications. in addition to the low noise level, mas9160 excels in dropout voltage (70 mv typical at 50 ma) and in very good crosstalk rejection. also its ripple rejection ability of 60 db at 1 khz exceeds that of competition. a wide range of values of equivalent series resistance (esr) of output capacitors can be used with mas9160. this esr range from a few m ? up to a couple of ohms combined with no minimum output current requirement makes the usage of mas9160 easier and low in cost. in order to save power the device goes into sleep mode when both regulators are disabled. an internal thermal protection circuit prevents the device from overheating. also the maximum output current is internally limited. 4/35/ 223
