MC7915BD2TG

MC7915BD2TG Description

The MC7915BD2TG from onsemi is a fixed-output negative voltage regulator designed to deliver a stable -15V output at up to 1A current. Housed in a D2PAK (TO-263) surface-mount package, this linear regulator is optimized for applications requiring reliable power conditioning with minimal external components. It features a low dropout voltage of 1.3V (typical at 1A) and 60dB PSRR (120Hz), ensuring robust performance in noisy environments. The device includes over-current and over-temperature protection, enhancing system reliability. Though marked as obsolete, it remains ROHS3 compliant and REACH unaffected, making it suitable for legacy designs.

MC7915BD2TG Features

• Fixed -15V output with 1A current capability for consistent power delivery.
• High PSRR (60dB at 120Hz) minimizes ripple in sensitive circuits.
• Low dropout voltage (1.3V typical at 1A) improves efficiency in low-input-voltage scenarios.
• Integrated protection: Over-current and over-temperature safeguards prevent damage under fault conditions.
• Surface-mount D2PAK package enables compact PCB layouts with efficient thermal dissipation.
• Wide industrial compliance: ROHS3, REACH unaffected, and MSL 1 (unlimited) for broad applicability.

MC7915BD2TG Applications

• Industrial power supplies: Stable negative rail generation for analog circuits, sensors, and control systems.
• Audio equipment: Low-noise voltage regulation for preamps, mixers, and signal processing.
• Test and measurement: Precision voltage references in lab instruments and data acquisition systems.
• Legacy systems: Maintenance and repair of older electronics requiring -15V regulation.
• Automotive electronics: Auxiliary power for infotainment or display systems (where obsolescence is manageable).

Conclusion of MC7915BD2TG

The MC7915BD2TG is a robust, high-performance negative voltage regulator ideal for applications demanding low noise, high PSRR, and reliable protection. While obsolete, its D2PAK package and 1A output make it a pragmatic choice for legacy designs or systems requiring minimal redesign. Engineers valuing simplicity, thermal efficiency, and compliance will find this regulator a dependable solution for industrial, audio, and instrumentation needs.
