APPENDIX
PIN DESCRIPTIONS
DESCRIPTION
Input supply.
Ground
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 ≥ 2.0μF ceramic) is needed from
this pin to ground to assure stability.
