Cross regulation reduction for multi-output power supply using TL431
Posted by: anoopps

Hi,
How can I reduce the cross-regulation issue using TL431 for my dual output power supply (+5v and -5V)....The PI expert software has no option if one output is negative...what can I do for this..? If I take the +5V line as +10V with respect to -5V line and GND line as +5V with respect to -5V line....then how can I get slow lane from GND line?
Regards,
Anoop
