For a project I'm working on I need a power supply of 3.3 V to supply power and current for 14 mini vibration motors that work on 3.3 V. Each motor is rated at 85 mA so I need to be able to deliver ~1.2 A.
A voltage regulator such as this one can deliver up to 800 mA current so I guess it is not a good choice. I was thinking of using voltage divider and a voltage follower circuit using an LM358 op-amp. What do you think about that solution? Here is my schematic for that:
With that circuit the output voltage at LM358 pin 1 will be fixed at ~3.3 V and the current will be as much as the phone charger can deliver(?), so if my phone charge is rated @5 V with 2 A, will I be able to deliver almost 2 A of current to the motors?
