7.3.2 Enable

The enable signal (V_EN) is an active-high digital control that enables the LDO when the enable voltage is past the rising threshold (V_EN ≥ V_IH(EN)) and disables the LDO when the enable voltage is below the falling threshold
(V_EN ≤ V_IL(EN)). The exact enable threshold is between V_IH(EN) and V_IL(EN) because EN is a digital control. In applications that do not use the enable control, connect EN to V_IN.
