UC2834DW

Voltage Regulators - Linear Regulator Controllers Overview

The UC2834DW is a high-efficiency linear regulator controller from the UC1834 family, designed for low input-output differential applications. It supports both positive and negative regulator designs using an external pass device. The IC features a 200mA sink or source drive output, adjustable current sense amplifier, and fault monitoring with under/over-voltage alerts. It includes a programmable delay for transient rejection and a crowbar drive output for over-voltage protection.

Voltage Regulators - Linear Regulator Controllers Procurement Notes

Verify the specific package type (SOIC-16) and temperature range (-40°C to +85°C) against system requirements. Confirm RoHS compliance status and lead finish details via the manufacturer's official documentation before procurement. Ensure compatibility with external pass devices and check for any lifecycle status changes such as obsolescence or replacement recommendations.

Voltage Regulators - Linear Regulator Controllers Selection Notes

Select this component when designing linear regulators requiring low voltage differentials at high currents. Consider the need for external pass devices and the benefits of integrated fault protection. Evaluate the programmable delay settings for transient immunity and ensure the thermal management strategy accommodates the power dissipation characteristics in the intended operating environment.

Voltage Regulators - Linear Regulator Controllers Part Context

The UC2834DW belongs to the UC1834 family of integrated circuits optimized for linear regulator applications. It shares functional similarities with UC1834 and UC3834 variants but offers specific temperature ratings suitable for industrial environments. The DW suffix indicates a 16-pin SOIC package, providing a surface-mount solution for compact circuit board designs.
