because voltage regulators have outputs declared as Output Power, but their ground pins are typically marked as Power Inputs. Therefore grounds are not considered driven by these voltage regulators. This is so so multiple regulators can share a common ground without errors caused by two Output Power pins being connected together. Power nets do not “jump” across components, so, components like passive inline 'Package_S0:SOIC-8_3.9x4.9_P1.27mm' 'U2270B' 'Package_S0:SOIC-16_3.9x9.9_P1.27mm' #regulators 'LP2985LV' 'Package_TO_SOT_SMD:SOT-23-5_HandSoldering' Viewing the Current Footprint
