... MIC5247 Applications Information Enable/Shutdown The MIC5247 comes with an active-high enable pin that can disable the regulator. Forcing the enable pin low disables the regulator and sends it into a “zero” off-mode-current state. In this state, current consumed by the regulator goes nearly to zero. Forcing the enable pin high enables the output volt- age. This part is CMOS and the enable pin cannot be left fl ...
