Quiescent current is 25µA typical, rising to 425µA max under all conditions. That 25µA Iq keeps the part viable for battery-operated or always-on subsystems where every microamp counts.
The 4-XFBGA / 4-FlipChip package is a 4-bump array, no leads. It requires a solder-paste stencil designed for the bump pitch; reflow profile follows standard JEDEC for lead-free (ROHS3).
