3, Pad
DESCRIPTION
Input supply.
Ground. The pad must be tied to GND.
Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator
into shutdown mode. 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. This allows output noise to be reduced to very low levels.
Adjustable 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. A small capacitor (total typical capacitance
≥
2.0
μ
F ceramic) is
needed from this pin to ground to assure stability.
Not internally connected. This pin must either be left open, or tied to GND.
