Overview
The LM336M-2.5/NOPB is a precision shunt voltage reference diode manufactured by Texas Instruments, belonging to the LM336 series. It provides a nominal reference voltage of 2.5 V with an initial accuracy of ±4%. Packaged in an 8-pin SOIC surface-mount format, it operates within a temperature range of 0°C to 70°C. The device features a temperature coefficient of 20 ppm/°C and supports a maximum output current of 10 mA. Input voltage requirements range from a minimum of 2.44 V to a maximum of 2.54 V, ensuring stable regulation for sensitive analog circuits.
Feature Summary
- Provides a fixed 2.5 V reference voltage suitable for precision applications
- Utilizes a shunt topology for stable voltage regulation
- Offers low temperature drift characteristics for consistent performance
Applications
- Analog-to-digital converter (ADC) reference inputs
- Digital-to-analog converter (DAC) voltage references
- Precision measurement instrumentation circuits
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the SOIC-8 package variant matches the target PCB footprint design. Ensure the ±4% accuracy class meets the system's tolerance requirements before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.5 V reference is required in a surface-mount configuration. Consider the ±4% initial accuracy and 20 ppm/°C temperature coefficient against circuit sensitivity needs. Verify that the 0°C to 70°C operating range aligns with the intended environmental conditions for the application.
Part Context
This part belongs to the LM336 family of two-terminal voltage references, which are widely used for their simplicity and reliability. The LM336 series offers various fixed voltage options and packaging styles, including through-hole and surface-mount variants, catering to diverse power management and signal conditioning requirements across industrial and consumer electronics.
Replacement Considerations
LM336M-2.5/NOPB is functionally equivalent to LM336M-25-NOPB. Both parts share identical electrical characteristics and pinouts within the same package.
