Typical Performance Characteristics Supply bypass capacitor is 0.1 µF and filter capacitor is

0.1 µF. (Continued)

Note 10: These curves represent a statistical average such that the noise is insignificant.

Typical Application Circuits In the application circuits, the 0.1 µF ceramic capacitor between pins 1 and 2

is used for bypassing, and the 0.1 µF ceramic capacitor between pins 3 and 4 is used for filtering. Shutdown (SD) is tied to

through a 10 kΩ resistor.
