MC78M05ACTG Description
MC78M05ACTG Description
The MC78M05ACTG from onsemi is a fixed-output linear voltage regulator designed to deliver a stable 5V output with a maximum input voltage of 35V and an output current capability of 500mA. Housed in a TO-220AB package, this obsolete but reliable component is RoHS3 compliant and features over-temperature and short-circuit protection, ensuring robust operation in demanding environments. With a PSRR of 80dB (120Hz), it effectively filters input noise, making it suitable for precision analog and digital circuits. Its wide operating temperature range (0°C to 125°C) and MSL 1 (Unlimited) rating further enhance its versatility for industrial and commercial applications.
MC78M05ACTG Features
- Fixed 5V Output: Ensures consistent voltage regulation for low-power systems.
- High Input Voltage Tolerance (35V): Accommodates fluctuating input sources.
- 500mA Output Current: Suitable for moderate-load applications.
- Robust Protection: Includes over-temperature and short-circuit safeguards for enhanced reliability.
- Low Noise Performance: 80dB PSRR minimizes ripple in sensitive circuits.
- Wide Temperature Range: Operates reliably from 0°C to 125°C, ideal for harsh environments.
- Through-Hole Mounting (TO-220AB): Facilitates easy integration in prototyping and production.
MC78M05ACTG Applications
This regulator is ideal for:
- Power Supplies: Stabilizing voltage for microcontrollers, sensors, and logic circuits.
- Industrial Control Systems: Providing clean power in PLCs, motor drivers, and automation equipment.
- Consumer Electronics: Used in audio amplifiers, set-top boxes, and low-power peripherals.
- Automotive Electronics: Auxiliary power regulation in non-critical automotive subsystems.
- Embedded Systems: Reliable voltage conversion for IoT devices and portable instruments.
Conclusion of MC78M05ACTG
The MC78M05ACTG is a dependable linear regulator offering a balance of performance, protection, and simplicity. While marked as obsolete, its high PSRR, robust thermal management, and wide input range make it a practical choice for legacy designs or applications requiring stable 5V power. Engineers seeking a cost-effective, no-frills solution for moderate-current applications will find this regulator well-suited, particularly in industrial and embedded systems where durability is critical.
