Overview
The TL4050A25IDBZT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 50 PPM/°C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- Provides high-precision voltage referencing with 0.1% initial accuracy for stable circuit performance.
- Designed for low-power applications through micropower consumption characteristics.
- Operates reliably across an extended industrial temperature range from -40°C to +125°C.
Applications
- Portable instrumentation requiring precise voltage standards
- Battery-powered measurement systems
- Data acquisition channels
Procurement Notes
Verify the specific suffix IDBZT corresponds to the SOT-23-3 package and commercial grade specifications. Confirm RoHS compliance status as indicated in official documentation. Ensure ordering quantities match available packaging formats such as cut tape or reel options provided by distributors.
Selection Notes
Select this component when a 2.5 V reference with 0.1% tolerance is required in a small footprint. Consider the 50 PPM/°C temperature drift for thermal stability needs. Evaluate the 15 mA maximum shunt current against load requirements to ensure proper operation within the specified electrical limits.
Part Context
This part belongs to the TL4050 series of precision micropower shunt voltage references. The series offers various output voltages and accuracy grades, including the A-grade variant with 0.1% initial accuracy. It serves as a key component in power management integrated circuits for maintaining reference stability.
Replacement Considerations
Check for direct substitutes like TL4050A25IDCKR for SC-70-5 packaging alternatives. Verify functional compatibility with TL4050A25QDBZR for automotive qualified versions if higher reliability standards are needed.
