i'm having issues with my pth08000 power regulator

[metalcookie]

i have everything wired correctly. i have checked this a million times. when the power regulator isn't wired directly up to the n64 it's reading 3.264, but when i wire it to the n64, i only read 2.756. i've done this with and without the 12 volt line wired up, and it still reads 2.756. i know my battery isn't the problem because i have wired the power circuit directly to three 9 volt power adapters - still nothing. the capacitor i am using is a 100 uf 25 volt. the resistor i am using is 2k. my screen is currently fried and i am not using a screen at the moment. i just have the n64 wired directly to an old a/v cable up to my portable dvd player. i have tested the board with the original power source, and it works.

is the capacitor i am using the problem? or is there something wrong with my power regulator?


please reply to this. it will be greatly appreciated

Could it be the effect of applying an actual load to the regulator?

Either has to be your batteries are too low amperage or the TI card is faulty.

how would i check the amperage with a multimeter?
it sounds stupid, but this is the first time my dad has actually let me use his multimeter, so i have little info on how it works. all i know how to do is check voltage and continuity.

i don't thin it is the batteries, because i got the same problem when i wired the regulator up directly to a power adapter rated at 9 volts
is it possible it is the capacitor or just a faulty ti regulator?

Simply written and easily understandable. If you don't learn how to use a multimeter you can't do this.

How many Ah or mAh are your power sources? More volts doesn't always mean more power?

SS

the batteries are 3300mAh, with two cells each rated at 3.7 volts. the rated voltage is 7.4 volts, but i can't ever get over 6.97 volts.
i have tested the regulator with it soldered directly to a power adapter rated at 9 volts, and still get the same problem, so i don't think it is the batteries, or maybe i just can't get a power adapter with high enough amps.
just a few minutes ago i ordered 3 more regulators. i'm going to test every one of them, and i still get the same problem i guess i need some new batteries with higher amperage

thanks for the link. i knew how to make it measure voltage and continuity, i just wasn't sure how to measure amps

How much amperage are you getting off the 9v adapter?
