An external bypass capacitor, connected to this terminal, in conjunction with an internal resistor, creates
a low-pass filter to further reduce regulator noise.
EN

I
The EN terminal is an input which enables or shuts down the device. When EN goes to a logic high, the
device will be enabled. When the device goes to a logic low, the device is in shutdown mode.
