Linear & Switching Voltage Regulators

L78M24CDT Description

The L78M24CDT is a fixed-output linear voltage regulator from STMicroelectronics, designed to deliver a stable 24V output at up to 500mA of continuous current. With an input voltage range extending up to 40V, this regulator is well-suited for applications requiring robust voltage conversion. Housed in a DPAK (TO-252) package, it offers efficient thermal dissipation and is ideal for surface-mount PCB designs. The device operates within a wide temperature range of 0°C to 125°C, ensuring reliability in demanding environments.

L78M24CDT Features

• Fixed 24V Output: Ensures precise voltage regulation without external adjustments.
• High Input Voltage Tolerance (40V Max): Accommodates fluctuating input conditions.
• 500mA Output Current: Sufficient for low-to-medium power applications.
• Built-in Protection: Includes over-current, over-temperature, and short-circuit protection for enhanced system safety.
• Low Quiescent Current (6mA): Improves efficiency in standby or low-load scenarios.
• Excellent PSRR (50dB at 120Hz): Minimizes noise and ripple for cleaner power delivery.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
• DPAK Package: Optimized for thermal performance and space-constrained designs.

L78M24CDT Applications

The L78M24CDT is ideal for systems requiring a stable 24V supply, such as:

• Industrial Control Systems: PLCs, motor drivers, and automation equipment.
• Telecommunications: Powering RF modules and base station components.
• Consumer Electronics: Audio amplifiers, display drivers, and set-top boxes.
• Automotive Electronics: Sensors and infotainment systems (non-safety-critical).
• Test & Measurement Equipment: Precision instruments requiring low-noise power rails.

Conclusion of L78M24CDT

The L78M24CDT stands out as a reliable, high-performance linear regulator, offering robust protection features, wide operating temperature range, and excellent noise suppression. While marked as obsolete, its proven design and DPAK packaging make it a viable choice for legacy systems or applications where replacement with newer alternatives is impractical. Engineers seeking a simple, no-frills 24V regulator with strong thermal characteristics will find this component well-suited for their needs.
