PRODUCTION DATA
1.2V Digital LDO requires one decoupling capacitor with a typical value of 4.7uF. The parasitic offered by different portion of the output path is illustrated in Figure 7-4. “RT1” and “RT2” are parasitic resistances offered by the ball to capacitor lead trace and the ground trace respectively. Similarly, “LT1” and “LT2” are parasitic inductances offered by the ball to capacitor lead trace and the ground trace respectively. “ESL1” and “ESR1” are the effective series inductance and resistance of the decoupling capacitor. Table 7-5 gives the minimum, maximum and typical values of the capacitance and the parasitic.
