I have been looking for suitable LDO regulators for this DAC project,as it will be battery powered for portable use.
I would value some input regarding this device:

Not having much experience with regulator specs[or electronics in general:xeye: ] the various specs do not mean a whole lot to me.
Cheers

I've used the REG101-5 for the TDA1543, Tent XO and logic chips.
Very low noise, small (SOT23-5), low drop.
:cool: |

Hi Rudolf
Thanks for the reply:D
They look like great little [VERY little] devices, the lack of cap
sensitivity is also very appealing.
I could not locate the 101s in the uk but found 113s to have pretty good spec also.
I can easily obtain these.
Cheers

Even Burr Brown specifies noise in the time domain without specifying the BW
yuck......
Rudolf, did you measure the noise ?

I didn't Guido. Limited in tools.
Do you want to measure it Guido ?
Got a board using this regulator and a socket for your XO. ;) |

Hi Rudolf,
I use a preamp (AD 797) and my HP3580A spectrum analyser. If you prefer to send the board with the reg 101, I am willing (and curious too) to measure it.
