POWER

+1.8V (Core voltage) - 1.8V regulator output for digital circuitry

on chip. Place a 0.1uF capacitor near this pin and connect the

capacitor from this pin to ground. In parallel, place a 4.7uF +/-

20% low ESR capacitor near this pin and connect the capacitor

from this pin to ground. X5R or X7R ceramic capacitors are

recommended since they exhibit an ESR lower than 0.1ohm at

frequencies greater than 10kHz.
