NAME ADJ FIXED
An external bypass capacitor, connected to this terminal, in conjunction with an internal
BYPASS 4 4
resistor, creates a low-pass filter to further reduce regulator noise.
Enable input that enables or shuts down the device. When EN goes to a logic high, the
EN 3 3 I
device is enabled. When the device goes to a logic low, the device is in shutdown mode.
