I need a pair of LDOs for positive/Negative 10V audio application

Other Parts Discussed in Thread: TPS7A49, TPS7A30, LM337

Hello, I am working on a power supply circuit for an audio design that requires +-10V, @ 0.1A Vin is +-12V (roughly)

I could use some help choosing a pair of LDOs that would fit that bill. Cost is of course a consideration, I don't need a designer LDO, the application isn't super critical, I just need a simple and decent LDO that will do the job.

Hi Steve,

Take a look at TPS7A30 and TPS7A49. These two LDOs are often paired together for applications like yours.

Very Respectfully,
Ryan

Thanks Ryan, I think those will work nicely. I wish there was version of the LM337 that was 150ma-200ma. These are great parts, but they are almost too nice. :)
