How can voltage be negative

WebIf OUT is grounded, the desired negative voltage can be achieved by selecting R3 and R4 such that: Vout- = - Vref * (1 + R4/R3) - Iadj * R4 To my knowledge of your application, I do not believe there is anything wrong with operating the regulator in this configuration since, as you have pointed out, there is no ground reference pin. WebKirchhoff's Voltage Law. Kirchhoff's Voltage Law: The sum of voltages around a loop is zero. Kirchhoff's Voltage Law can be written as, \large\displaystyle \sum_n v_n = 0 n∑v n = 0. where n n counts the element voltages around the loop.
