Pin Description
Pin Name
BIAS
Description
The bias pin is used to provide the low current bias voltage to the chip which operates the internal
circuitry and provides drive voltage for the N-FET.
The regulated output voltage is connected to this pin.
This is both the power and analog ground for the IC. Note that both pin three and the tab of the
TO-220 and TO-263 packages are at ground potential. Pin three and the tab should be tied together
using the PC board copper trace material and connected to circuit ground.
The high current input voltage which is regulated down to the nominal output voltage must be
connected to this pin. Because the bias voltage to operate the chip is provided seperately, the input
voltage can be as low as a few hundered millivolts above the output voltage.
This provides a low power shutdown function which turns the regulated output OFF. Tie to V
BIAS

this function is not used.
