1.All specifications valid at normal input voltage, full load and +25°C after warm-up time unless otherwise stated.
2.Ripple & Noise are measured at 20MHz of bandwidth with 0.1UF & 47UF parallel capacitor.
OUTPUT NOISE
The output noise is measured with 10μF tantalum capacitor and 1μF ceramic capacitor across output.
