Regulator Input. Supply voltage can range from 2.7V to 11.5V.
Ground. These pins function as heatsinks, only in the SOIC package. All GND pins must be soldered to the
circuit board for proper power dissipation. Connect to large copper pads or planes to channel heat from the IC.
Shutdown, active low. Switch logic levels in less than 1µs with the high level above the OFF threshold.
Feedback for Setting the Output Voltage. Connect to GND to set the output voltage to the preselected 3.3V
or 5V. Connect to an external resistor network for adjustable output operation.
Regulator Output. Fixed or adjustable from 1.25V to 11.0V. Sources up to 500mA for input voltages above 4V.
