DESCRIPTION
Input supply
Ground
Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts
the regulator into shutdown mode. Refer to the
section under
Applications Information for more details. EN can be connected to IN if not used.
Fixed voltage versions only—connecting an external capacitor to this pin bypasses
noise generated by the internal bandgap, reducing output noise to very low levels.
Adjustable voltage version only—this is the input to the control loop error amplifier,
and is used to set the output voltage of the device.
Output of the Regulator. There are no output capacitor requirements for stability.
