onsemi MC7815BDTRKG +15V regulator, 1A linear voltage regulator IC
The MC7815BDTRKG from onsemi is a fixed-output, positive-voltage linear regulator designed to deliver a stable +15V DC output with an input voltage range of 17V to 35V. Built with bipolar technology, this regulator provides up to 1A of output current while maintaining low dropout voltage and high ripple rejection. It features internal thermal overload protection and short-circuit current limiting, ensuring reliable operation in harsh conditions. The device is housed in a TO-252-3 (DPAK) package, offering efficient heat dissipation for power applications. With a typical line regulation of 0.01%/V and load regulation of 0.3%, it is well-suited for analog and digital circuits requiring precise voltage regulation.
Linear Voltage Regulator Key Features
● Fixed +15V Output: Stable voltage regulation for analog/digital systems.
● Wide Input Range: 17V to 35V, compatible with 24V industrial supplies and unregulated DC sources.
● High Current Capability: Up to 1A output with short-circuit protection.
● Thermal Overload Protection: Prevents damage from excessive heat.
● Low Dropout Voltage: Minimizes power loss in regulation.
● High Ripple Rejection: Reduces noise in sensitive circuits.
● Robust Packaging: TO-252-3 (DPAK) for efficient thermal performance.
Applications
The MC7815BDTRKG is commonly used in power supplies for industrial control systems, automotive electronics, audio amplifiers, and test equipment. Its ability to maintain stable voltage under varying loads makes it ideal for microcontroller power rails, sensor interfaces, and analog signal conditioning circuits. The high ripple rejection is particularly beneficial in noise-sensitive audio and measurement applications.
Selection Advantages
This regulator is favored for its simplicity, reliability, and cost-effectiveness in delivering fixed +15V power. Unlike switching regulators, it provides noise-free output, making it preferable for analog circuitry. The built-in protection features enhance durability in industrial and automotive environments, while the DPAK package simplifies thermal management without requiring additional heatsinks in moderate-load applications.
