5.3
In order to reduce the quiescent current to a minumum, the TLE4254 can be switched to stand-by mode by setting
the adjust/enable input “ADJ/EN” to “low”.
In case the pin “ADJ/EN is left open, an internal pull-down resistors keeps the voltage at the pin low and therefore
ensures that the regulator is switched off.
