This circuit offers excellent ripple ... The regulator 78xxr, U1 utilizes the action of zener diode ZD1 which is in parallel with the potentiometer, R1. The tuning action of R1 produces a variable ...

For the longest time, Zener diode regulators have been one of those circuits that have been widely shared and highly misunderstood. First timers have tried to use it to power up their experiments ...

For many years, designers used Zener diodes as simple shunt voltage regulators ... A voltage reference is at the heart of all voltage-regulator circuits, and can provide higher current with ...
