PIN CONFIGURATIONS
PIN DESCRIPTIONS
ADJ
This pin, when grounded, sets the output voltage to that set by the internal feedback resistors. If ex-
ternal feedback resistors are used, the output voltage will be: (See Application Circuit)
EN
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.
GND
Reference ground.
VIN
Input voltage. For regulation at full load, the input to this pin must be between (VO + 0.7V) to 5.5V.
Minimum VIN = 2.2V.

This pin is the power output of this device.
