Fixed Negative Voltage Regulators
This IC regulator supplies a hard and ouput that is fast that is negative. The 7900 number of IC regulators is generally useful for this purpose. This series (7900) is the counterpart that is negative-voltage of show [See Table below]. Observe that 7900 series provides fixed regulated voltages from â€“ 5V to â€“ 24 V. Figure shows how IC that is 7912 connected to supply a d.c that is fixed. output of â€“ 12 V. The input that is unregulated is negative Vi is linked to ICâ€™s IN terminal as well as ICâ€™s OUT terminal provides â€“ 12 V. Capacitors utilized in the circuit perform the exact work that is same in a tough and fast regulator that is good.
