ZENER DIODES

VOLTAGE REGULATION A voltage regulator circuit automatically maintains the output voltage of a power supply constant, regardless of - a change in the load - a change in the source voltage ZENER DIODES The simplest of all voltage regulators is the zener diode voltage regulator. A zener diode is a special diode that p is optimized for operation in the g breakdown region. ZENER DIODE CIRCUIT The zener diode is typically connected reverse biased, in parallel with the load. Resistor Rs limits current to zener. zener ZENER DIODE CHARACTERISTICS In the forward region, the zener diode acts like a regular silicon diode, with a 0.7 volt drop...
