Note 2:
Operation beyond the specifications listed in the Electrical Characteristics may exceed the power dissipation ratings of
the device.
Note 3:
Wide temperature range circuit of Figure 5 using Sprague surface-mount capacitors.
Note 4:
Standby current includes all external component leakage currents. Capacitor leakage currents dominate at TA= +85°C.
