Notes:

a. Full = - 40 °C to 85 °C.

b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum (- 40 °C to 85 °C).

c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

d. Minimum operating voltage is determined by the battery’s capability to provide energy as it is deeply discharged.

e. Vnom equals programmed output voltage.
