NOTE

1. Ripple & noise are measured at 20MHz of bandwidth by using a 12”

twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

2. Tolerance : includes set up tolerance, line regulation and load regula-

tion.

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

wise noted
