I have a device with ICs in it that are rated to 3.6V or 3.7V for normal use, and I am powering it with a 3.7V (nominal voltage) Li-Ion battery.
The battery fully charges to ~4.2V. Powering a circuit with this fully charged Li-Ion battery means I will have overvoltage conditions after charging, until the battery is drained lower than ~3.7V.
What is the simplest way to limit the battery voltage to 3.7V or below? Zener diode (how?) ?
Thanks!
