hi, i want low voltage regulators for +15V in 2.5V/50mA out, low noise(<50uV),and -15V in -2.5V/50mA
out,low noise(<-50uV), devices that
in +15V or -15V and output +/- 2.5V/50mA are ideal.

can anyone suggest me some?

(for me, it is most hard to find suitable negative output regulator)

Best Regards
Li
