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) Volts

R2

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 all four pins on the SO-8 device for heatsinking. Use the tab on the SOT-223, TO-220

and TO-263 devices 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.

The pin is the power output of the device.
