... The MIC49150 requires a minimum of output capaci- tance to maintain stability. However, proper capacitor selection is important to ensure desired transient response. The MIC49150 is specifically designed to be stable with virtually any capacitance value and ESR. A 1µF ceramic chip capacitor should satisfy most app- lications. Output capacitance can be increased without bound. See “ ...

... Power MSOP-8 Thermal Characteristics One of the secrets of the MIC49150’s performance is its power MSOP-8 package featuring half the thermal resistance of a standard MSOP-8 package. Lower thermal resistance means more output current or higher input voltage for a given package size ...

... I OUT Where V Enable The fixed output voltage versions of the MIC49150 feature an active high enable input (EN) that allows on- off control of the regulator. Current drain reduces to “zero” when the device is shutdown, with only microamperes of leakage current. The EN input has TTL/CMOS compatible thresholds for simple logic interfacing ...
