Question:
Is it necessary to maintain 5V power supply voltage in Stand-by mode ?
Answer:
In software stand-by, the 5V supply is necessary because the CPU registers are maintained. However its OK to reduce the power supply voltage in hardware stand-by because only the RAM contents are preserved. The minimum voltage to hold the RAM contents is 2V.
