MC79L05ACPRAG  

Linear & Switching Voltage Regulators

MC79L05ACPRAG Description

The MC79L05ACPRAG from onsemi is a fixed-output negative linear voltage regulator delivering -5V at up to 100mA load current. Designed for precision voltage regulation in low-power circuits, it features a TO-92-3 through-hole package, making it suitable for prototyping and compact designs. With an operating temperature range of 0°C to 125°C, this regulator ensures stable performance across industrial and consumer applications. Its 49dB PSRR (120Hz) minimizes noise, while built-in over-temperature and short-circuit protection enhances reliability. The device complies with ROHS3 and REACH environmental standards and is supplied in Tape & Reel (TR) packaging for automated assembly.

MC79L05ACPRAG Features

• Fixed -5V Output: Ensures consistent voltage regulation for sensitive analog/digital loads.
• Low Dropout Voltage: 1.7V (Typ) @ 40mA maximizes efficiency in low-input-voltage scenarios.
• High PSRR (49dB): Effectively suppresses input ripple, ideal for noise-sensitive applications.
• Robust Protection: Includes thermal shutdown and short-circuit protection for fail-safe operation.
• Wide Temperature Range: Operates from 0°C to 125°C, suitable for harsh environments.
• Compact TO-92-3 Package: Space-efficient and easy to integrate into through-hole designs.

MC79L05ACPRAG Applications

• Power Supply Stabilization: Used in negative rail generation for op-amps, sensors, and audio circuits.
• Industrial Control Systems: Reliable voltage reference for PLCs, motor drivers, and instrumentation.
• Consumer Electronics: Powers low-current analog sections in audio amplifiers, set-top boxes, and displays.
• Battery-Powered Devices: Efficient regulation in portable equipment due to low quiescent current.
• Automotive Electronics: Suitable for non-critical 12V/24V systems where stable -5V bias is required.

Conclusion of MC79L05ACPRAG

The MC79L05ACPRAG stands out for its high PSRR, robust protection, and compact form factor, making it a preferred choice for low-power negative voltage regulation. Its wide operating temperature range and compliance with environmental standards ensure versatility across industrial, automotive, and consumer applications. Engineers favor this regulator for its reliability in noise-sensitive designs and ease of integration, particularly in space-constrained through-hole layouts. For cost-effective, precision voltage regulation, the MC79L05ACPRAG delivers consistent performance with minimal external components.
