6. Dropout depends on LDO and DC−DC PFET R
and inductor DCR.

7. The current limit is the peak (maximum) current.
8. Guaranteed by design. Maximum values are based on simulation results with 50% COUT derating; not tested in production. Voltage tran-
sient only. Assumes C = 24.7 mF (1x4.7 mF for regulator and 2x10 mF for PA decoupling capacitors).
