= 5V, T
A
= +25°C, unless otherwise noted.)
Note 3: Commercial temperature range external component values in Table 2.
Note 4: Wide temperature range external component values in Table 2.
Note 5: Supply current includes all external component leakage currents. External capacitor leakage currents dominate at T
A
> +85°C.
C3 and C4 = Sanyo Oscon through-hole capacitors.
Note 6: Operation beyond the specifications listed in the
Electrical Characteristics
may exceed the power dissipation ratings of the device.
