Pin Descriptions
Pin Name Pin Desciption
ADJ This pin, when grounded, sets the output voltage to that set by the internal feedback resistors. If external
feedback resistors are used, the output voltage will be (See Application Circuits on page 1):

Enable Input. Pulling this pin below 0.4V turns the regulator off, reducing the quiescent current to a fraction of
its operating value. The device will be enabled if this pin is left open. Connect to VIN if not being used.
Reference ground. Use the tab (electrically connected to GND) for heatsinking.
Input voltage. For regulation at full load, the input to this pin must be between (VO + 0.7V) and 5.5V. Minimum
VIN = 2.2V.
This pin is the power output of the device.
