... Enable function (ST1L05B, ST1L05C and ST1L05D only) The ST1L05B, ST1L05C and ST1L05D features an enable function. When the EN voltage is higher than 2 V the device is ON, and lower than 0.8 V the device is OFF. In shutdown mode, consumption is lower than 1 µA. The EN pin has an internal pull-up, which means that it can be left floating not used. ...
