validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LP3961, LP3964 products can provide 800-mA output current with 2.5-V to 7-V input voltage. An input
capacitor of at least 68-uF is required. A minimum 33-uF output capacitor is required for loop stability. Pin SD
must be tied to input if not used. For LP3961, the ERROR pin should be pulled high through a pull up resistor; if
this function is not used, ERROR pin must be connected to ground . For LP3964, if the sense option is not
required, the SENSE pin must be connected to the OUT pin.
