LM336B-5.0

Overview

The LM336B-5.0 is a precision shunt voltage reference integrated circuit manufactured by TAEJIN Technology. It provides a fixed 5.0V reference output with an initial accuracy of ±1% or ±2%. The device operates in a TO-92 three-pin through-hole package, suitable for surface and leaded mounting. It functions as a low temperature coefficient zener diode, maintaining stability across an operating temperature range of 0°C to 70°C. Key electrical parameters include a maximum input voltage of 5.1V, minimum input voltage of 4.9V, and an output current capability of 10mA. The unit features a thermal resistance barrier layer temperature limit of 100°C.

Feature Summary

• Provides stable 5.0V reference voltage with high precision
• Operates as a programmable shunt regulator
• Low temperature coefficient for thermal stability
• Monolithic IC construction for reliability

Applications

• Precision voltage regulation circuits
• Analog-to-digital converter references
• Portable instrument power supplies
• Battery-powered measurement devices

Procurement Notes

Verify the manufacturer designation on the component marking, as TAEJIN produces this part alongside other vendors like Fairchild and Texas Instruments. Confirm the specific tolerance grade (±1% vs ±2%) required for your application, as datasheets may list both variants under similar part numbers. Ensure the TO-92 package dimensions match your PCB footprint requirements before ordering.

Selection Notes

Select this component when a fixed 5V reference is needed in a cost-sensitive, through-hole design. It is suitable for applications requiring moderate precision where ±1% or ±2% accuracy suffices. Consider the 10mA current limit and 70°C operating range when designing thermal management. It serves as a direct replacement for legacy LM336-5.0 designs in standard industrial equipment.

Part Context

The LM336 series represents a family of precision shunt voltage references widely used in analog electronics. The LM336B-5.0 specifically denotes the 5.0V variant with B-grade accuracy. Manufactured by TAEJIN Technology, it competes with similar offerings from major semiconductor firms. The device utilizes bandgap or zener technology to maintain a constant voltage drop across its terminals regardless of current variations within its operational limits.

Replacement Considerations

LM336Z-5.0/NOPB (Texas Instruments) offers equivalent 5V shunt regulation in TO-92. LM336-5.0 (Fairchild/ON Semiconductor) is a direct functional substitute. Verify pinout compatibility and tolerance specifications when swapping between manufacturers.
