a.
The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
b.
Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
c.
Part requires minimum start–up of VIN w 2.0 to ensure operation down to 1.8 V.
d.
For VIN v 2.7 V see typical ON/OFF threshold curve.
