DESCRIPTION
Regulated output voltage pin. A small 1
μ
F ceramic capacitor is needed from this pin to ground to assure
stability. See
Input and Output Capacitor Requirements
in the
Application Information
section for more
details.
Select pin. Driving VSET below 0.4V selects preset output voltage V
OUT1
. Driving VSET over 1.2V selects
preset output voltage V
OUT2
.
No connection.
Enable pin. Driving EN over 1.2V turns on the regulator. Driving EN below 0.4V puts the regulator into
shutdown mode, thus reducing the operating current to 100nA, nominal.
Ground pin (connect DRV thermal pad to ground)
Input pin. A small capacitor is needed from this pin to ground to assure stability. See
Input and Output
Capacitor Requirements
in the
Application Information
section for more details.
