Description
Enable Input. Drive EN high to turn on the regulator; drive it low to turn off the
regulator. For automatic startup, connect EN to IN.
Ground.
Regulator Input Supply. Bypass IN to GND with a 4.7 μF or greater capacitor.
Regulated Output Voltage. Bypass OUT to GND with a 4.7 μF or greater capacitor.
Sense. Measures the actual output voltage at the load and feeds it to the error
amplifier. Connect SENSE as close as possible to the load to minimize the effect
of IR drop between the regulator output and the load.
Soft Start. A capacitor connected to this pin determines the soft start time.
Track. The output follows the voltage applied at the TRK pin. See the Theory of
Operation section for a more detailed description.
Adjust. A resistor divider from OUT to ADJ sets the output voltage.
The exposed pad on the bottom of the SOIC package and the LFCSP package. EP
enhances thermal performance and is electrically connected to GND inside the
package. User is recommended to connect EP to the ground plane on the board.
