LM236AH-5.0/NOPB

Overview

The LM236AH-5.0/NOPB is a fixed 5V shunt voltage reference manufactured by Texas Instruments, originally under the National Semiconductor brand. It features an initial accuracy of ±1% and operates within a temperature range of -25°C to 85°C. The device utilizes a TO-46-3 metal can package and supports a maximum output current of 10 mA with a minimum cathode current of 600 µA for regulation.

Feature Summary

• Provides a stable 5V reference voltage with high initial accuracy
• Utilizes a hermetic metal can package for environmental protection
• Designed for shunt regulation applications

Applications

• Precision analog circuit references
• Voltage monitoring systems
• Test and measurement equipment

Procurement Notes

Verify the manufacturer designation as Texas Instruments despite the National Semiconductor model history. Confirm the TO-46-3 metal can package type and ±1% accuracy grade. Ensure the operating temperature range meets system requirements of -25°C to 85°C. Check for lead-free compliance status associated with the NOPB suffix.

Selection Notes

Select this component when a hermetically sealed metal can package is required for harsh environments. The ±1% accuracy offers higher precision than standard plastic packages. Consider the 10 mA current capability for load driving needs. Evaluate the TO-46-3 form factor against available board space constraints.

Part Context

This part belongs to the LM236 series of integrated reference circuits. It serves as a precision voltage reference alternative to Zener diodes. The NOPB suffix indicates a lead-free and RoHS-compliant manufacturing process. The device maintains performance characteristics consistent with the broader LM236 family specifications.
