Current rating for Gmm-u1 / Gms-d1 / PA6B modules.
« on: June 14, 2010, 12:42:07 PM »
Q: For what current shall the linear regulator of Gmm-u1 / Gms-d1 / PA6B modules be rated?

According to the data sheet, the maximum consumption of GlobalTop Gmm-u1 / Gms-d1 / PA6B modules is around 53 mA with everything on (except the 3D-FIX pin floating).
Taking into account that the 3D-FIX can source up to 14 mA, the maximum is around 67 mA.
However, we typically suggest that you use an LDO rated for a current equal to three times the maximum current consumption (53 mA x 3 = about 150 mA).
