Need Help about PSU Voltages (3.3 V)

A lot of group regulated power supplies are "tuned" to keep the 12v proportional to the 5v and maintain regulation with the amount of current consumed on 5v. So without any load on 5v, you may see exactly 5.00v and 12.5v on 12v, but if your PC consumes let''s say 10-20w on 5v, the 5v may drop to 4.95v and 12v will also drop a bit to 12.4v, and

How can I supply 5v voltage to circuit in a portable way?

First, if it''s really that important that this device be small and the batteries minimal, design it for 2.5-3.3 V power. Then you can use a coin cell directly. You will also find that most parts that run from this power voltage will draw less power than when running from 5 V. Second, you can convert between voltages with a switching power supply.

power

A lower voltage means lower power consumption: an HCMOS IC at 3.3 V will typically consume 50 % or less power than the same circuit at 5 V. So you create a microcontroller which internally runs at 3.3 V to save power, but has 5 V I/Os. (The I/O may also be 5 V-tolerant; then it works at the 3.3 V levels, but won''t be damaged by 5 V on its inputs.

3.3V DC Power Supplies

Power factor shows how effectively a power supply draws AC power from the main electrical supply. The higher the power factor— up to a maximum score of 1— the lower your operating cost. Efficiency describes how good a power supply is at converting the AC power it draws from your main electrical supply into DC power.
