Notes

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 regulation.

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted
