Overview
The LM4040BELT-5.0 is a low-power, high-accuracy shunt voltage reference manufactured by STMicroelectronics. It provides a stable 5.0 V output with an initial accuracy of ±0.2% at 25°C. The device features ultra-low operating current of 10 µA and very low low-frequency noise of 10 µV p-p. It operates within an industrial temperature range of -40°C to +125°C with a maximum temperature coefficient of 70 ppm/°C. The component is housed in a SOT-23-3 surface-mount package and supports a maximum shunt current of 15 mA.
Feature Summary
- Ultra-low power consumption suitable for battery-operated designs
- High precision with ±0.2% initial accuracy
- Very low low-frequency noise performance
- Stable operation with capacitive loads
Applications
- Portable battery-powered equipment
- Data acquisition systems
- Instrumentation
Procurement Notes
Verify the specific suffix BELT corresponds to the required tape-and-reel packaging format and the 5.0 V output voltage variant. Confirm that the SOT-23-3 package dimensions meet the target PCB layout constraints. Ensure the ±0.2% accuracy grade meets the system requirements before finalizing the order.
Selection Notes
Select this component when a precise 5.0 V reference is needed in space-constrained portable devices. The low quiescent current makes it ideal for extending battery life. The wide operating temperature range ensures reliability in harsh industrial environments. Verify that the load conditions remain within the specified shunt current limits.
Part Context
This part belongs to the LM4040 family of micro-power shunt voltage references from STMicroelectronics. The family offers various fixed output voltages and accuracy grades. The LM4040 series is designed for applications requiring high stability and low power consumption in compact packages.
Replacement Considerations
Check for direct pin-compatible substitutes with identical voltage and accuracy specifications. Verify thermal characteristics and package compatibility if replacing with components from other manufacturers.
