TL4050B50QDBZRQ1

Overview

The TL4050B50QDBZRQ1 is a precision micropower shunt voltage reference from Texas Instruments, designed for automotive applications. It provides a fixed output voltage of 5V with an initial tolerance of ±0.2% and a maximum temperature coefficient of 50ppm/°C. The device operates within an ambient temperature range of -40°C to +125°C and is qualified under AEC-Q100 standards. It features low dynamic impedance and wideband noise characteristics, requiring no external capacitors for stability across all capacitive loads.

Feature Summary

AEC-Q100 qualified for automotive grade 1 environments
Stable with all capacitive loads without external capacitors
Low dynamic impedance and low noise performance
Extended operating temperature range capability

Applications

Data-acquisition systems
Power supplies and power-supply monitors
Automotive electronics
Precision audio equipment

Procurement Notes

Verify the specific suffix QDBZRQ1 matches the required automotive qualification and package type. Confirm the B grade designation aligns with the necessary 0.2% tolerance specifications. Ensure the ordering quantity meets the manufacturer's standard packaging requirements for the SOT-23-3 variant.

Selection Notes

Select this component when a stable 5V reference is required in space-constrained automotive designs. The B grade offers tighter tolerance than C grade options while maintaining micropower efficiency. Consider the low minimum cathode current for battery-powered applications where standby consumption is critical.

Part Context

This part belongs to the TL4050-Q1 family of shunt voltage references. The family includes various output voltages and tolerance grades (A, B, C) packaged in SOT-23-3 and SC-70 formats. The Q1 designation indicates automotive qualification, distinguishing it from commercial variants within the same electrical architecture.
