+5 Vdc, nominal (+4.75 to +5.25 Vdc).
50 mA, typical at +5 Vdc. Average power dissipation is 0.25 W, typical.
Supply must be capable of sourcing 100 mA, minimum.
Total noise and ripple requirement must be less than 100mV (p-p) for frequencies
below 1MHz, and less than 50mV (p-p) for frequencies above 1MHz.
