A7900 Series Negative-Voltage Regulators

Category: Electronics, Regulators, Texas Instruments HighPerformance Analog

Overview

The A7900 Series Negative-Voltage Regulators are integrated-circuit voltage regulators designed by Texas Instruments, created to provide solutions for applications requiring fixed-negative-voltage regulation. The series is intended to complement Series HA7S 900 and cater to applications that involve on-card regulation to mitigate noise and distribution issues associated with single-point regulation.

Features

Key features of the A7900 Series include:

3-Terminal Regulators: Simplified design for ease of use.
High Power-Dissipation Capability: Ensures reliable operation under various conditions.
Output Current up to 1.5 A: Suitable for a range of power requirements.
Internal Short-Circuit Current Limiting: Protects the device from overload damage.
No External Components Required: Minimizes additional parts and simplifies circuit design.
Output Transistor Safe-Area Compensation: Provides stability and reliability.
Internal Thermal-Overload Protection: Prevents thermal runaway and damage.
