DESCRIPTION
MAS9162 is a low dropout voltage regulator with an enable/disable pin, which allows device to be turned off or on by pulling control to low or high.
No external bypass capacitor is needed for achieving the low noise level of 30 µVrms. In addition to the noise levels, MAS9162 excels in dropout voltage (95 mV typical at 50 mA) and in start-up time (typically 10 µs from start-up to within ±1% of VOUT(NOM)).
The Equivalent Series Resistance (ESR) range of output capacitors that can be used with MAS9162 is very wide. This ESR range from a few mΩ up to a couple of Ohms combined with no minimum output current requirement makes the usage of MAS9162 easier and low in cost. Also the minimum output capacitance requirement is very low. This combined with very short start-up time makes it possible to switch the regulator off and on even in timing critical and/or noise sensitive applications.
