LT1019CN8-5#PBF

Voltage Reference Overview

The LT1019CN8-5#PBF is a shunt precision voltage reference manufactured by Analog Devices Inc., housed in an 8-pin PDIP package. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.2% and a temperature coefficient of 20 ppm/°C. The device operates within a supply voltage range of 6.5 V to 40 V, drawing a maximum supply current of 1.5 mA and a typical quiescent current of 650 µA. It supports a maximum cathode current of 10 mA and requires a minimum operating current of 800 µA. The component functions across a temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Delivers stable 5 V reference output with high initial accuracy
• Operates as a shunt regulator with low quiescent current consumption
• Compatible with through-hole mounting for standard PCB layouts

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition system voltage standards
• Calibration equipment reference circuits
• Instrumentation signal conditioning power supplies

Voltage Reference Procurement Notes

Verify the specific suffix designation to confirm the package type and temperature grade. Confirm RoHS compliance status prior to integration. Check authorized distributor availability as this part may be subject to limited supply conditions or discontinuation notices. Ensure the ordering code matches the required PDIP-8 configuration for your design.

Voltage Reference Selection Notes

Select this component when a fixed 5 V shunt reference is required with moderate precision. Consider the 20 ppm/°C temperature coefficient for thermal stability needs. Verify that the input voltage remains above 6.5 V to ensure proper regulation. Evaluate the 10 mA load current capability against circuit requirements.

Voltage Reference Part Context

This part belongs to the LT1019 series of precision voltage references from Analog Devices. It is functionally similar to other shunt references but distinguished by its specific 5 V output and PDIP-8 packaging. The series is designed for applications requiring reliable voltage standards without the complexity of series regulators.
