ZXRE125FR

Overview

The ZXRE125FR is a micropower bandgap voltage reference providing a fixed output of 1.22V with a tolerance of 3%. It operates within a current range of 30µA to 5mA and features a typical temperature coefficient of 20ppm/°C. The device is housed in an E-Line (TO-92 style) package, suitable for through-hole mounting. It maintains stability under capacitive loads and exhibits wideband noise of 60µVrms.

Feature Summary

• Provides a stable 1.22V reference voltage with high tolerance to capacitive loads
• Operates efficiently at low quiescent currents starting from 30µA
• Maintains excellent performance across the full operating temperature range

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems
• A/D and D/A converters

Procurement Notes

Verify the specific E-Line package suffix 'R' corresponds to the required through-hole configuration. Confirm that the 3% tolerance meets circuit requirements. Check for tape and reel availability by adding the 'TA' suffix if automated assembly is needed. Ensure compatibility with existing board layouts designed for ZRA124 or ZRA125 replacements.

Selection Notes

Select this component when a through-hole voltage reference is required instead of surface mount options. The E-Line package offers pin-for-pin compatibility with older ZRA series references. Consider the 3% tolerance and 20ppm/°C temperature coefficient for general precision applications where space constraints are less critical than in SOT23 designs.

Part Context

This part belongs to the ZXRE125 family of micropower voltage references. It serves as a direct replacement for the ZRA124 and ZRA125 series. The family includes SOT23, SO8, and E-Line packages with varying tolerances from 0.5% to 3%.

Replacement Considerations

ZXRE125FR replaces ZRA125FR.
