PIN DESCRIPTIONS

Pin Name Pin Functiom

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):

VO = 1.200 (R1 + R2) Volts

R2

EN

GND

VIN

VO

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 TO-220

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.

This pin is the power output of the device.
