Need equivalent to 74HC541

Hey all....hoping someone can help me with this. I have a couple voltage regulators I'm trying to cross but not having much luck.
The first is:
A1
AS1117L-18
B0640 25
The second is:
A1
AS1117L-33
B0640 28
I know the AS stands for Alpha Semiconductor, and I think I've found a datasheet for the AS1117L-33, just can't find anything for the -18. Ultimately I'm looking to cross these over to parts that I can get now, as all I'm finding similar are AZ1117 regulators.
If anyone can assist... -
I try to substitute the RT6575B with TPS51285A,
it seems to work but it is slightly warmer, the board does not start due to other problems so but not sure if replacement is possible... -
So a while back, to deal with the fan noise of the old blower style shrouds on the reference cards, I chucked it and installed the monster that is a Raijintek MORPHEUS 8069, with a couple Noctuas on it. Did the job but quite unwieldy tbh.
Anyone know which boards would have a compatible shroud for it? I know the EVGA used the reference board but wondering if any other manufacturers did. I want to put something sensible back on it, but I'm having a hard time getting hold of even a faulty reference board for a reasonable price. -
Hi,
I'm getting some conflicting information and thought I'd toss it out to all of you for input.
What I have is a TTC-104 thermistor. This is part of a temp sense circuit that will drive a small 12v fan to cool components mounted to SMPS heat sink.
The physical diameter of the piece is 5.1mm measured with a caliper.
Other than what you see in the pic, there is no other writing on the part.
My research of the TTC-104 says it should read 100 ohms at 25C. Out of circuit measurements have it at approximately 100k. It does change as the temp changes.... -
Hello,
I would like to know the reference of a QFN-20 because the reference marked on the chip does not give anything...
PC Reference : HP Pavilion - 15-cs0006nf
Motherboard : DA0G7BMB6D0 rev D
Reference marked on the chip: AWVAIL
Type : QFN-20
I didn't find a boardview or repair schematics
Thanks in advance...
