UC2836DW

Overview

The UC2836DW is a low-dropout voltage controller manufactured by Texas Instruments, operating within an input voltage range of 6 V to 40 V. It supports adjustable output voltages from 2.5 V to 35 V with a maximum output current capability of 600 mA. The device functions with a quiescent supply current of 3.7 mA and is rated for operation between -25°C and +85°C. It utilizes an 8-pin SOIC surface-mount package.

Feature Summary

• Provides high-efficiency regulation control for linear power supplies
• Supports adjustable output voltage configurations via external components
• Designed for surface-mount installation in compact circuits

Applications

• Low dropout regulator circuit design
• High efficiency linear power supply systems
• General purpose voltage regulation modules

Procurement Notes

Verify the manufacturer designation as Texas Instruments rather than Unitrode, as the latter entity was acquired. Confirm the specific suffix 'DW' corresponds to the SOIC-8 package variant. Ensure compliance with RoHS directives and moisture sensitivity levels prior to integration into final assemblies.

Selection Notes

Select this component when designing adjustable LDO controllers requiring wide input voltage tolerance up to 40 V. Consider the 600 mA output limit and 3.7 mA quiescent current for power budgeting. The SOIC-8 package suits applications prioritizing space efficiency over through-hole mounting requirements.

Part Context

This part belongs to the UC2836 series of low-dropout voltage controllers produced by Texas Instruments. It serves as a control element for linear regulators, distinct from switching controllers or motor drivers found in other product lines. The device focuses on precise voltage regulation rather than high-frequency switching operations.
