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 – 5V to – 24 V. Figure shows how IC that is 7912 connected to supply a d.c that is fixed. output of – 12 V. The input that is unregulated is negative Vi is linked to IC’s IN terminal as well as IC’s OUT terminal provides – 12 V. Capacitors utilized in the circuit perform the exact work that is same in a tough and fast regulator that is good.
