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):
VO
=
1.200 (R1 + R2)
R2
Volts
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. Note: The GND pin and the exposed die pad must be connected together at the IC pin.
Use the exposed die pad on the device for heatsinking.
VIN Input voltage. For regulation at full load, the input to this pin must be between (VO + 0.5V) and 5.5V. Minimum
VIN = 2.2V.
VO
The pin is the power output of the device.
