Negative Voltage Regulator:

Connections for getting negative voltage regulator are shown in Fig. 2.116.

Negative Voltage Regulator

An external PNP transistor, Q1 is connected. Resistances can be from 1 kΩ to 10 kΩ.

Negative Voltage Regulator

If magnitude of -Vi is less than 9V, connect VCC+ and VC to a positive supply such that VCC+ to VCC- is greater than 9V, for proper functioning of the IC.
