SUMMARY
To power three 5V devices from a vehicle's 12V auxiliary power, a voltage regulator rated for 3-5A and capable of handling input voltages up to 17V is required. Each device draws a total of 2.75A, which is within the capacity of the vehicle's power system. A suitable voltage regulator can be found at Digi-Key, such as part number 576-1121-ND. Additionally, a heatsink is necessary to manage heat dissipation effectively.
