TS4061AICT-1.25

Overview

The TS4061AICT-1.25 is a shunt voltage reference IC manufactured by STMicroelectronics, designed for precision applications requiring stable reference voltages in compact surface-mount packages. This component provides a fixed output voltage of 1.25V with an initial accuracy tolerance of ±0.1%, ensuring high precision across operating conditions. It operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 35ppm/°C to maintain stability against thermal variations. The device draws a cathode current of 12µA and can supply up to 15mA of output current. Packaged in the SC-70 (SOT-323) format, it integrates noise performance specifications including 10µVp-p from 0.1Hz to 10Hz and 95µVrms from 10Hz to 10kHz.

Procurement Notes

Verify part authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and moisture barrier status upon receipt. Check for RoHS compliance documentation and ensure storage conditions meet specified limits to prevent degradation. Validate lot codes against current production notices to avoid obsolete stock issues.

Selection Notes

Select this component when a fixed 1.25V reference is required with tight tolerance and low power consumption. Consider the SOT-323 package size constraints and thermal environment. Evaluate noise requirements against the specified 10µVp-p low-frequency noise if used in sensitive measurement chains. Ensure the application current does not exceed the 15mA maximum output limit.
