MC79L12ABPRAG  

Linear & Switching Voltage Regulators

MC79L12ABPRAG Description

The MC79L12ABPRAG from onsemi is a fixed-output negative linear voltage regulator designed to deliver a stable -12V output with a maximum current of 100mA. Housed in a TO-92-3 package and supplied in Tape & Reel (TR), this device is optimized for through-hole mounting, making it suitable for prototyping and industrial applications. It features a low dropout voltage of 1.7V (typical @ 40mA) and excellent PSRR of 42dB (120Hz), ensuring reliable performance in noisy environments. With built-in over-temperature and short-circuit protection, the MC79L12ABPRAG offers robust safety for sensitive circuits.

MC79L12ABPRAG Features

• Fixed Negative Output: Delivers a precise -12V with tight regulation.
• High PSRR (42dB): Minimizes ripple and noise for clean power delivery.
• Low Dropout Voltage (1.7V @ 40mA): Enhances efficiency in low-input-voltage scenarios.
• Protection Mechanisms: Includes thermal shutdown and short-circuit protection for enhanced reliability.
• Wide Compliance: ROHS3 Compliant and REACH Unaffected, meeting environmental standards.
• Through-Hole Package (TO-92-3): Simplifies assembly in legacy and industrial designs.

MC79L12ABPRAG Applications

• Power Supply Regulation: Ideal for negative voltage rails in analog and mixed-signal circuits.
• Industrial Control Systems: Suitable for sensor interfaces, instrumentation, and control modules requiring stable negative bias.
• Consumer Electronics: Used in audio amplifiers, signal conditioning, and legacy equipment.
• Prototyping & Education: The TO-92 package makes it a preferred choice for breadboard and lab applications.

Conclusion of MC79L12ABPRAG

The MC79L12ABPRAG stands out as a reliable, cost-effective solution for negative voltage regulation in low-to-medium power applications. Its high PSRR, low dropout, and robust protection features make it superior to basic regulators, while its through-hole design ensures compatibility with a wide range of systems. Whether for industrial, consumer, or educational use, this regulator delivers consistent performance with minimal external components.
