Hi all,
I have a circuit which consists of some quad op-amps and other low power ICs.
As for the input supply, I am going to use the supply from microprocessor development boards (either 3.3V or 5V).
As an extra protection for the circuit, I was planning to include a 5.1V zener diode so it won't be damaged in case of accidental use of voltages above 5V (up to 12V).
As for the zener diode, I was planning to use the TZM5231B-GS08, together with a 400ohms resistor.
Could anyone please suggest if this is the right circuit to implement and if the zener and resistor combination is correct? Also, this zener is listed as "small signal diode". Will it work for regulating the supply (few mA)?
Thanks in advance.
