Overview
The LM3411M5X-5.0/NOPB is a precision secondary regulator and driver manufactured by Texas Instruments, originally under National Semiconductor. It functions as a shunt voltage reference with a fixed output of 5V. Key electrical parameters include a maximum output current of 15 mA, a typical quiescent current of 85 µA, and an input voltage range up to 20 V. The device offers a tolerance of ±1% or ±2% depending on the specific grade, with a dropout voltage of approximately 1.0 V. It operates within a temperature range of -40°C to 85°C.
Feature Summary
- Precision secondary regulation capability for stable voltage control
- Low quiescent current consumption for energy efficiency
- Fixed 5V output option ensuring consistent reference levels
Applications
- Precision analog circuit biasing
- Secondary voltage regulation in power supplies
- Reference voltage generation for data converters
Procurement Notes
Verify the manufacturer designation, as the part was originally from National Semiconductor but is now produced by Texas Instruments. Confirm the specific suffix (NOPB) indicates lead-free status. Ensure the package type matches the SOT-23-5 (M5) footprint requirements for your PCB layout. Check for any recent Product Discontinuance Notifications or Process Change Notifications that may affect long-term availability.
Selection Notes
Select this component when a low-cost, fixed 5V shunt reference is required with moderate load current capabilities. Consider the ±1% or ±2% tolerance options based on application accuracy needs. Evaluate the 15 mA output current limit against peak load demands. Compare quiescent current specifications if battery life is a critical constraint in the design.
Part Context
This device belongs to the LM3411 family of precision secondary regulators. These components are designed to replace traditional Zener diodes in applications requiring higher stability and lower noise. The M5 package denotes a small outline transistor-style housing suitable for space-constrained designs.
Replacement Considerations
The LM3411AM5X-5.0/NOPB is a verified alternative offering potentially tighter tolerance specifications. Verify pin compatibility and thermal characteristics before substitution.
