I'm trying to use LT3032 in my design to regulate +/-15V supply voltages coming from DC/DC swithing regulator.
The output voltage of LT3032 is set to +/-14V with voltage setting resistors. However, output voltage is about +/-12V. I discovered that BYPN and BYPP voltages are a little off.
I measured BYPN is about -78mV and BYPP is about 79mV.
As it is stated in the datasheet these pins are high impedance, sensitive nodes that need attention. I tried to prevent leakage into these pins by clearing the ground and power planes beneath them, but I still get this huge error. What could cause this error?
Thanks in advance!
