Table 1. PIN DESCRIPTIONS
DESCRIPTION
Input to the device.
Ground.
Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the
regulator into standby mode, thereby reducing operating current.
Fixed voltage versions only. An external capacitor connected to this terminal bypasses
noise generated by the internal bandgap, lowering output noise.
Adjustable voltage version only. The voltage at this pin is fed to the error amplifier. A
resistor divider from OUT to FB sets the output voltage when in regulation.
This is the regulated output voltage. A small capacitor is needed from this pin to ground
to assure stability; a 1.0 F ceramic capacitor is adequate.
Not connected. This pin can be tied to ground to improve thermal dissipation.
