The MC78D05CDT-TP from MCC is a fixed 5V linear regulator capable of delivering 1A of output current. Housed in a DPAK package, it offers a simple and reliable solution for stepping down higher voltages to a stable 5V rail. With a quiescent current of 8 mA and a PSRR of 62dB at 120Hz, it is well-suited for industrial and consumer applications requiring clean, regulated power.
- Simple Fixed Output: No external resistor divider needed; 5V output is ready to use.
- High Current Handling: 1A output supports a wide range of loads from logic to small actuators.
- Good Ripple Rejection: 62dB PSRR at 120Hz effectively filters AC mains ripple.
- Surface-Mount Package: DPAK package is easy to solder and suitable for automated assembly.
Industrial Control Systems
The 5V fixed output and 1A capability make it suitable for powering logic circuits, relays, and small motors in industrial controllers where a stable 5V rail is required.
Consumer Appliances
With a DPAK package and 1A output, it can power microcontrollers and display drivers in washing machines, microwaves, and other home appliances.
Automotive Aftermarket Electronics
The robust 5V output can power sensors, dashboard displays, and aftermarket infotainment modules from a 12V vehicle battery.
Power Supply Modules
It can serve as a post-regulator in multi-output power supplies, providing a clean 5V rail from a higher intermediate voltage.
Test and Measurement Equipment
The 62dB PSRR at 120Hz helps reduce mains hum in bench-top instruments requiring a stable 5V reference.
LED Lighting Drivers
For constant-voltage LED strips, this regulator can provide a regulated 5V supply from a 12V or 24V input.
