TL4050B10IDBZT

Overview

The TL4050B10IDBZT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10V with an initial accuracy tolerance of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 50ppm/°C. Key electrical specifications include a maximum shunt current of 15mA, a cathode current of 103µA, and a noise level of 150µVrms from 10Hz to 10kHz. It is housed in a surface-mount SOT-23-3 package.

Feature Summary

Provides high-precision voltage regulation with ±0.2% initial accuracy for stable reference applications.
Designed for low-power consumption with a micropower cathode current specification.
Ensures thermal stability through a controlled temperature coefficient across the operating range.

Applications

Analog-to-digital converter (ADC) reference inputs
Digital-to-analog converter (DAC) voltage references
Portable instrumentation requiring precise voltage standards
Battery-powered measurement systems

Procurement Notes

Verify the specific suffix 'IDBZT' to confirm the SOT-23-3 package and industrial temperature grade (-40°C to +85°C). Ensure the 'B' designation matches the required ±0.2% accuracy tier. Confirm RoHS compliance status and moisture sensitivity level requirements against the target assembly process specifications before ordering.

Selection Notes

Select this component when a 10V fixed reference is required in a compact SOT-23-3 footprint. The ±0.2% accuracy suits applications demanding tighter tolerances than standard commercial grades. Consider the 15mA max shunt current limit for load driving capabilities and verify that the 103µA quiescent current aligns with system power budget constraints.

Part Context

This part belongs to the TL4050 family of precision micropower shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades. The TL4050B series specifically targets higher precision needs compared to lower-grade variants, providing reliable performance in space-constrained portable electronics and industrial control circuits.
