Overview
The LM236AH-5.0/NOPB is a precision shunt voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed 5V output with an initial accuracy of ±1%. The device operates within a temperature range of -25°C to +85°C and features a maximum cathode current of 10mA, with a minimum regulation current of 600µA. It is housed in a TO-46-3 metal can package (TO-206AB) designed for through-hole mounting.
Feature Summary
- Provides a stable fixed 5V reference voltage suitable for precision applications
- High initial accuracy of ±1% ensures reliable performance across operating conditions
- Robust TO-46-3 metal can package offers durability and environmental protection
Applications
- Precision analog signal conditioning circuits
- Data acquisition systems requiring stable voltage references
- Test and measurement equipment calibration
Procurement Notes
Verify the specific suffix 'AH' against the official datasheet to confirm the exact accuracy grade and temperature range specifications. Ensure the TO-46-3 package dimensions match the target PCB footprint. Confirm RoHS compliance status as indicated in supplier documentation before finalizing procurement.
Selection Notes
Select this component when a fixed 5V reference with high accuracy is required in a ruggedized metal can package. Consider the 600µA minimum current requirement for biasing resistor calculations. Evaluate thermal management needs given the through-hole metal case construction compared to plastic packages.
Part Context
This part belongs to the LM236 series of integrated reference circuits from Texas Instruments. It serves as a drop-in replacement for older Zener diode references, offering superior stability and lower noise. The series includes various voltage options and accuracy grades to suit different precision requirements.
Replacement Considerations
Check for LM336Z-5.0/NOPB if a plastic TO-92 package is acceptable instead of the metal TO-46-3. Verify pinout compatibility between legacy Zener diodes and this integrated circuit to ensure correct circuit integration.
