Function
The input of the regulator. Bypass to
ground through at least 1µF ceramic
capacitor.
The output of the regulator. Bypass to
ground through at least 2.2µF
ceramic capacitor. For improved ac
load response a larger capacitor is
recommended.
Ground
Adjustable voltage version only – a
resistor divider from this pin to the
OUT pin and ground sets the output
voltage.
Enable input, active high
No connection
