X60003BIG3Z-50T1

Overview

The X60003BIG3Z-50T1 is a precision voltage reference utilizing Intersil’s proprietary Floating Gate Analog (FGA) technology, housed in a standard 3-lead SOT-23 package. It provides a stable 5.000V output with an initial accuracy of ±1.0mV and a low temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 5.1V to 9.0V, drawing only 500nA of quiescent current. It features a very low dropout voltage of 100mV at no load and supports 10mA source and sink currents. The component offers 5kV ESD protection and functions reliably across a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix 'BIG3Z' against official documentation to confirm pinout and marking details, as ordering suffixes can indicate variations in tape-and-reel specifications or moisture sensitivity levels. Confirm RoHS compliance status and lead-free plating requirements with the manufacturer's latest datasheet before finalizing procurement, ensuring alignment with assembly process constraints.

Selection Notes

Select this component when designing circuits requiring ultra-low power consumption alongside high precision, such as battery-operated portable instruments. The 5.000V output and ±1.0mV initial accuracy make it suitable for high-resolution data conversion references. Ensure the input voltage remains within the 5.1V to 9.0V range to maintain the specified 100mV dropout performance and stable regulation characteristics.

Part Context

This part belongs to the X60003 FGA™ voltage reference family, which leverages floating gate technology for enhanced precision. The series includes variants with different output voltages and accuracy grades. The X60003 series is designed to replace conventional references in applications demanding superior stability and lower power, offering a compact SOT-23 solution for space-constrained designs.

Replacement Considerations

Check for direct cross-reference part numbers from Intersil/Renesas or other manufacturers offering equivalent FGA or XFET technology. Verify that any substitute matches the 5.000V output, ±1.0mB grade accuracy, 10ppm/°C tempco, and SOT-23-3 package dimensions to ensure mechanical and electrical compatibility without circuit redesign.
