Function
Ground
5.1V Reference voltage with 20mA current capability.
An external resistor connected between the unregulated input voltage and this pin and
a capacitor connected from this pin to groundfix the switching frequency. (Line feed
forward is automatically obtained)
Stepdown regulator output
Unregulated DC inputvoltage
A capacitor connected between this pin and OUT allows to drive the internal VDMOS
E/A output to be used for frequency compensation
Stepdown feedback input. Connecting directly to this pin results in an output voltage of
3.3V. An external resistive divider is required for higher output voltages.
