The MC7805CD2TG is a classic fixed 5V linear regulator from onsemi, capable of delivering up to 1A of output current. It features a typical dropout voltage of 2V at full load and a quiescent current of 6.5mA. With excellent PSRR of 83dB at 120Hz, it effectively filters out power supply ripple. Housed in a D2PAK-3 package, it is designed for applications requiring higher power dissipation and easy heatsinking.
- High Output Current: The 1A capability makes it suitable for powering multiple ICs and peripherals in a system.
- Excellent Ripple Rejection: The 83dB PSRR at 120Hz effectively eliminates mains hum and rectifier ripple, providing clean DC power.
- Wide Input Voltage Range: Accepts input voltages from 7V to 35V, making it versatile for various power supply configurations.
- Robust Thermal Performance: The D2PAK package with exposed tab allows efficient heat dissipation, enabling continuous operation at high loads.
Industrial Power Supplies
The MC7805CD2TG provides a robust 5V rail for industrial control systems, PLCs, and motor controllers. Its 1A output capability and wide input voltage range (up to 35V) make it ideal for converting unregulated DC supplies from transformers or rectifiers.
Consumer Electronics
In DVD players, set-top boxes, and gaming consoles, this regulator powers logic circuits and microcontrollers. The 83dB PSRR at 120Hz effectively filters full-wave rectifier ripple, ensuring stable operation of digital systems.
Test and Measurement Equipment
For benchtop multimeters, oscilloscopes, and signal generators, the MC7805CD2TG provides a clean 5V reference for analog and digital circuits. The D2PAK package allows for easy heatsinking, enabling continuous operation at high ambient temperatures.
Automotive Aftermarket Electronics
In car audio systems, GPS trackers, and dash cameras, this regulator converts the vehicle's 12V battery voltage down to 5V. The 2V dropout ensures reliable operation even when the battery voltage drops during engine cranking.
