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.

All specifications are typical at nominal input, full load, and 25°C unless other-

wise noted
