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).
