Minimum current draw

i’m going to put 3 shruthis in one case (SSM), ie 1x complete with controller and 2x stock for polychaining.
is there a huge difference in current draw between the positive and negative rails?
if so i’ll probably use 2 separate transformers.
what is actually the minimum draw for each rail? (per unit)

The LT1054 cannot source more than 100mA, so the negative rail is below that. As a rule of thumb, use 10mA per IC.

More current is drawn on the positive rail, to power the LCD (around 100mA) and the LEDs (10 to 20 mA per LED).

thank you!
