8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

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.
