The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. Typical values at 25_C ambient.
Ground pin current includes the IC supply current and the current to drive the linear regulator or bypass switch.
