Overview
The LM236DE4-2-5 is a shunt voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 2.49V with a tolerance of ±2%. The device operates within a temperature range of -25°C to 85°C and is housed in an 8-SOIC package. It supports a cathode current of up to 400 µA and can deliver an output current of 10 mA. The component is RoHS compliant and has a moisture sensitivity level of 1.
Feature Summary
- Provides a stable fixed reference voltage for precision applications
- Operates as a shunt regulator requiring minimal external components
- Suitable for surface-mount assembly in compact designs
Applications
- Precision analog-to-digital converter references
- Voltage monitoring circuits
- Portable battery-powered instrumentation
Procurement Notes
Verify the specific suffix DE4 against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering information matches the required tolerance and package type. Cross-reference with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a low-cost, fixed 2.5V reference is required for shunt regulation applications. Consider the ±2% tolerance and operating temperature range to ensure it meets system accuracy requirements. Verify that the SOIC package fits the PCB layout constraints and thermal management needs.
Part Context
This part belongs to the LM236 family of shunt voltage references from Texas Instruments. It is functionally similar to the LM336 series but may differ in specific electrical characteristics or packaging options. The DE4 suffix typically indicates a specific tape and reel packaging variant or manufacturing revision within the standard product line.
Replacement Considerations
Direct substitutes include the LM236DR-2-5 and LM236DRE4-2-5, which share the same core functionality and pinout. Verify that any replacement maintains the required ±2% tolerance and 8-SOIC package dimensions.
