NOTE

The combined ESR of the capacitors used on 1.2 V pins (V1V2 in the picture) shall be in

the range of 30 mΩ to 150 mΩ. The minimum value of the ESR is constrained by the

resonance caused by the external components, bonding inductance, and internal

decoupling. The minimum ESR is required to avoid the resonance and make the regulator

stable.
