Electrical Characteristics for the LM4668 (Note 1) (Continued)

Note 8: Datasheets min/max specification limits are guaranteed by design, test, or statistical analysis.

Note 9: Shutdown current is measured in a normal room environment. The SHUTDOWN pin should be driven as close as possible to GND for minimum shutdown

current.

Note 10: Please refer to “Under Voltage Protection” on page 8 under “General Features.”
