Supplier Device Package DPAK

The MC78M08CDT-TP is a fixed 8V linear regulator from MCC, delivering up to 500mA in a DPAK package. With a dropout of 2V at 350mA and 6mA quiescent current, it offers reliable regulation for industrial and automotive applications.

  • Stable 8V output: Fixed voltage eliminates external resistor divider, simplifying design.
  • 500mA current capability: Supports moderate loads for multiple peripheral circuits.
  • DPAK package: Excellent thermal performance for continuous operation.
  • Low quiescent current (6mA): Reduces standby power in battery-backed systems.

8V Rail for Industrial Control Boards

Provides a stable 8V supply for analog front-ends and op-amp circuits in industrial controllers, with 500mA capacity for multiple ICs.

Bias Supply for Power Management

Use as a bias rail for gate drivers or supervisory circuits where 8V at up to 500mA is required, with low noise from linear regulation.

Post-Regulation for Switching Converters

Clean up noisy DC-DC output to 8V for sensitive audio or measurement equipment, leveraging the 2V dropout at 350mA.
