LM78XX is a good option to solve your problem, but I strongly suggest you to investigate on LM2596 and mic29302. These regulators are much better than the old (but always effective) LM78XX series. If you are new to electronics, I recommend you to start with the newest available components. You will need some additional capacitors for these regulators but it's nothing hard, you will find all required information in the datasheets. Also, using LM2596 you can adjust the output voltage by changing the resistors values, so you can re-use these components in future projects. LM78XX series has defined output voltages that cant be changed.

LM317 12v to 5v converter: 5v to 3.3v converter with LM1117/ ASM1117 Certain electronic devices, components, IC’s, sensors or microcontrollers designed to work on 3.3V DC supply as a power source.

While working on some projects with standard power supply (say) 5 volts or higher, some modules/ circuits would require lower 3.3Volts. Here, in this post we will be discussing some of the simplest voltage regulator circuits designed using linear regulator IC LM/ AMS1117, LM3940, etc.

These circuits can also be used to step down or reduce 5V/ 9v available supply potential to 3.3v so as to use it with microcontroller, modules or any IC’s. A 5v to 3.3v converter circuit can be implemented using various ways like using linear voltage regulator, boost converter/ switching converter, resistor/ voltage divider, zener regulator, etc. You could choose the right circuit or module according to the requirements of the applications.

It is always recommended to use reliable linear power converters like ASM-LM1117/ LM3940/ XL6009 etc.
