... The MIC49300 requires a minimum of output capacitance to maintain stability. However, proper capacitor selection is important to ensure desired transient response. The MIC49300 is specifi cally designed to be stable with virtually any capacitance value and ESR. A 1µF ceramic chip capaci- tor should satisfy most applications. Output capacitance can be increased without bound ...

... OUT Enable The fi xed output voltage versions of the MIC49300 feature an active high enable input (EN) that allows on-off control of the regulator. Current drain reduces to “zero” when the device is sn}tñ◊wn, with only microamperes of leakage current. The EN input has TTL/CMOS compatible thresholds for simple logic interfacing ...
