... IRU3007 of the 1500mF, 6MV1500GX type Sanyo capacitors. With Rs=5mV, the maximum ESR becomes 9.5mV which is equivalent to 4 caps. Another important consideration is that if a trace is being used to implement the resistor, the power dissipated by the trace increases the case temperature of the output capacitors which could seri- ously affect the life span of the output capacitors ...
