Overview
The LM336BDR-2.5 is a two-terminal shunt voltage reference integrated circuit manufactured by Texas Instruments, housed in an 8-pin SOIC surface-mount package. It provides a nominal output voltage of 2.49 V with an initial accuracy of ±4%. The device operates within a temperature range of 0°C to 70°C and features a temperature coefficient of 20 ppm/°C. It supports a maximum shunt current of 10 mA and requires a minimum operating current of 600 µA for regulation.
Feature Summary
- Provides stable reference voltage via two-terminal shunt topology
- Offers fixed output voltage precision suitable for calibration applications
- Designed for surface-mount integration in compact electronic circuits
Applications
- Precision analog-to-digital converter (ADC) reference sources
- Voltage regulator feedback networks
- Temperature compensation circuits requiring stable bias voltages
Procurement Notes
Verify the specific suffix 'B' against the manufacturer's official datasheet to confirm it denotes the standard commercial grade variant rather than a specialized industrial or military specification. Ensure the ordering part number matches the exact pinout and tolerance requirements defined in the component documentation before finalizing procurement orders.
Selection Notes
Select this component when a low-cost, surface-mount shunt reference is required for general-purpose applications. It is appropriate for designs where a 4% tolerance is acceptable and operation is limited to the commercial temperature range. Consider alternative packages if higher thermal performance or tighter accuracy is needed.
Part Context
This component belongs to the LM336 family of two-terminal voltage references, which are widely used as economical alternatives to Zener diodes. The LM336 series offers improved stability and lower dynamic impedance compared to traditional discrete Zener devices, making it a standard choice for basic reference needs in consumer and industrial electronics.
Replacement Considerations
LM336M-2.5/NOPB: Similar shunt reference with identical electrical characteristics but available in SOIC-8 package; verify temperature range compliance.
FAQ
What is the minimum current required for the LM336BDR-2.5 to regulate?
The device requires a minimum operating current of 600 µA to maintain proper voltage regulation.
Does the LM336BDR-2.5 support adjustable output voltage?
No, the LM336BDR-2.5 is a fixed-output device providing a nominal 2.49 V reference voltage.
