Overview
The LM336DT is a precision 2.5V voltage reference monolithic integrated circuit manufactured by STMicroelectronics. It operates similarly to a 2.5V Zener diode, featuring a low temperature coefficient and a dynamic impedance of 0.2Ω. The device includes a third pin that enables adjustment of the reference voltage and temperature coefficient. It supports a wide operating current range from 400µA to 10mA and guarantees temperature stability with fast turn-on characteristics.
Feature Summary
- Provides precise 2.5V regulation with low temperature coefficient
- Features adjustable reference voltage and temperature coefficient via third pin
- Exhibits low dynamic impedance of 0.2Ω for stable performance
Applications
- Precision voltage reference circuits
- Analog-to-digital converter references
- Temperature compensated oscillator circuits
Procurement Notes
Verify the specific suffix 'DT' against the official STMicroelectronics datasheet to confirm package type and tape-and-reel specifications. Ensure the component matches the exact electrical parameters defined in the public documentation before procurement. Cross-reference the manufacturer part number to avoid confusion with similar shunt regulator devices.
Selection Notes
Select this component when a stable 2.5V reference is required with minimal temperature drift. The adjustable feature allows optimization for specific circuit conditions. Verify that the operating current falls within the specified 400µA to 10mA range for optimal performance and stability in the target application design.
Part Context
The LM336 series consists of precision 2.5V regulator diodes designed as voltage references. These monolithic ICs offer superior performance compared to standard Zener diodes due to their low dynamic impedance and guaranteed temperature stability. The family includes variants like LM236, providing options for different operational requirements while maintaining core precision characteristics.
Replacement Considerations
Public confirmed substitute part numbers include LM336-2.5 from Texas Instruments and Fairchild Semiconductor. Other compatible references include MCP1525 from Microchip Technology. Verify pinout compatibility and electrical specifications before substitution.
