SNVS872D August 2012 – August 2018 LMZ21700
The enable pin (EN) is weakly pulled down internally through a 400 kΩ resistor to keep EN logic low when the pin is floating. The pulldown resistor is not connected when EN is set high. Once the voltage on the enable pin (EN) is set high the Nano Module will start operation. If EN is set low ( < 0.3 V ) the LMZ21700 will enter shutdown mode. The typical shutdown quiescent current is 1.5 μA.
