Output voltage load regulation
Figure 14. VOUT = 3.3 V load regulation shows negligible output voltage variation (normalized to the value
measured at IOUT = 0 A) over the entire output current range for the L6986H with VOUT = 3.3 V, measured on the
L6986H evaluation board (see Section 6.7 Application board).

High-side switch resistance vs. input voltage
Figure 15. Normalized RDS(on),HS variation shows the high-side switch RDS(on) variation over the entire input
voltage operating range normalized at the value measured at VIN = 12 V (see Section 3 Electrical
characteristics).
