NOTES

1. Ripple & Noise is measured by using a 20MHz bandwidth

oscilloscope and terminating the output with a 47uF electrolytic capacitor

paralleled with a 0.1uF ceramic capacitor.

may adversely affect long term reliability. Proper operation under conditions

other than the standard operating conditions is neither warranteed nor implied.
