3. The TI LM4040 2.5-V voltage-reference curve shows its high voltage accuracy even when biased well below 100 µA. Using the same 12-V example as above, but with 75 µA for I z instead of 5 mA ...

We’re quite sure that all hobbyists have used the 7805 voltage regulator at least once in their lives. They are a simple way to regulate 7V+ voltages to the 5V that some of our low power proj… ...

Now's the time to give up on a pure zener diode and go to a temperature-compensated zener. The 1N935 has a zener voltage of 9.075V; a tolerance of 5%; a temperature coefficient of 2 mV/°C; and a zener ...

Voltage Regulator Offers Overload Indication, Short-Circuit Protection. ... The series chain of Zener diode D1 (a 1N4737A) and green LED D2 (part of the two-color LED D2/D4) ...
