HAZ8Mxx Positive-Voltage Regulators

Category: Electronics, Regulators, Texas Instruments HighPerformance Analog

Overview

The HAZ8Mxx series, introduced by TEXAS INSTRUMENTS in June 1976 and revised in January 2015, encompasses a range of fixed-voltage integrated-circuit voltage regulators. These devices are particularly designed for an array of applications, requiring reliable voltage regulation and integration into various electronic devices. Notable for their ability to supply a stable output current of up to 500 mA, these components are an important solution for managing on-card regulation issues such as noise attenuation and distribution problems derived from single-point regulation.

Key Features

No External Components: The HAZ8Mxx regulators are designed to function without the need for additional external parts, simplifying design and deployment.

Internal Thermal-Overload Protection: To prevent overheating, these regulators are fitted with an internal thermal-overload protection mechanism.

High Power-Dissipation Capability: These devices can handle a considerable amount of power dissipation, making them suitable for a wide range of uses.

Internal Short-Circuit Current Limiting: The built-in short-circuit current limiting feature adds an extra layer of safety, ensuring the regulator is safeguarded from potential damage caused by short circuits.

Output Transistor Safe-Area Compensation: This feature is intended to protect the output transistor from operating outside its safe operating area, further enhancing the regulator’s reliability.

Applications

The versatility of the HAZ8Mxx series makes it suitable for integration into numerous types of electronic systems, including:

On-Card regulation systems, which benefit from minimized noise and distribution issues.
Portable Devices that require a compact and reliable power regulation solution.
Computing & Servers, where stable power is critical to ensure consistent operation and performance.
Telecommunications equipment that demands reliable voltage regulation for optimal functionality.
