PIN DESCRIPTIONS
DESCRIPTION
Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown
mode. Refer to the Shutdown section under Applications Information for more details. EN must not be left
floating and can be connected to IN if not used.
Adjustable voltage version⁽¹⁾ only—this pin is the input to the control loop error amplifier, and is used to set the
output voltage of the device.
Ground
Unregulated input supply
Not connected
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.
Regulator output. A 1.0-μF or larger capacitor of any type is required for stability.
