Ground pin. The back tab is also ground and serves as the package
heatsink. It should be soldered to the circuit board copper to remove
excess heat from the IC.
This pin is for V
set using an external resistor divider connected to ADJSD. The output
voltage is determined by the following formula
where R1 is the ground-side resistor and R2 is the upper resistor of the
divider. Connect these resistors to the V
regulation.
In addition, functions as a Shutdown pin. Apply a voltage higher than V
0.6V to this pin to simultaneously shutdown both V
The outputs are restored when the voltage is lowered below V
low-leakage diode in series with the Shutdown signal is recommended to
avoid interference with the voltage adjustment setting.
