LT1019CS8-5#TRPBF

Voltage Reference Overview

The LT1019CS8-5#TRPBF is a precision shunt voltage reference IC manufactured by Analog Devices Inc. It provides a fixed output voltage of 5V with an initial tolerance of ±0.2%. The device operates within an input voltage range of 6.5V to 40V and draws a supply current of 1.5mA. It supports a maximum cathode current of 800µA and can source up to 10mA output current. Key noise specifications include 2.5ppm peak-to-peak (0.1Hz to 10Hz) and 2.5ppm RMS (10Hz to 1kHz). The temperature coefficient is 20ppm/°C, and it functions within a junction temperature range of 0°C to 70°C. The component is housed in an 8-SOIC package.

Voltage Reference Feature Summary

• Provides stable precision reference voltage with low drift characteristics
• Features low noise performance suitable for sensitive analog circuits
• Capable of sourcing significant load current while maintaining regulation

Voltage Reference Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter references
• Calibration equipment requiring stable voltage standards

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct voltage output and package type. Check RoHS compliance status as required by project specifications. Ensure input voltage constraints are met during system design to prevent damage or regulation failure.

Voltage Reference Selection Notes

Select this component when a fixed 5V precision reference is required in an SOIC-8 package. Consider the 20ppm/°C temperature coefficient and 1.5mA quiescent current against application needs. Verify that the 6.5V minimum input voltage requirement fits the available power rails. Compare noise specs with other series options if lower drift is necessary.

Voltage Reference Part Context

This part belongs to the LT1019 family of precision shunt voltage references from Analog Devices. The CS8 designation specifies the commercial temperature range and SOIC-8 package style. The -5 suffix denotes the fixed 5V output version. Other variants in the series offer different fixed voltages such as 2.5V or 10V, sharing similar electrical characteristics and pinouts.

Voltage Reference Replacement Considerations

LT1019CS8-5#PBF offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel.
