For potential divider, exactly at centre of R4 the output d.c. voltage level must be zero. 4. Opamp frequency range must be higher than fmax of oscillator. 6.15 Introduction to Voltage Regulators The voltage regulator circuit keeps the output voltage constant inspite of changes in the load current or input voltage. Its input is unregulated pulsating d.c. voltage obtained from filter and rectifier. Its output is constant d.c. voltage which is almost ripple free.

The transformer steps down the a.c. voltage down to the level required for the desired d.c. output. The rectifier converts a.c. voltage to a d.c. voltage. The filter circuit is used after the rectifier to reduce the ripple content in the d.c., to make it smoother. Still then the d.c. voltage usually has some ripple or a.c. voltage variation. This voltage is called unregulated
