DESCRIPTION
1
IN
Regulator Input. Supply voltage can range from 2.7V to 11.5V.
2, 3, 6, 7
GND
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.
4
OFF
Shutdown, active low. Switch logic levels in less than 1μs with the high level above the OFF threshold.
5
SET
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.
8
OUT
Regulator Output. Fixed or adjustable from 1.25V to 11.0V. Sources up to 500mA for input voltages above 4V.
