TS821BILT

Overview

The TS821BILT is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a stable 1.225V output. It features an initial accuracy of ±0.5% and a maximum temperature coefficient of 120 ppm/°C. The device operates within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum operating current of 12 mA and a minimum cathode current of 45 µA. It is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

Provides a fixed 1.225V reference voltage with high precision for accurate circuit regulation.
Features ultra-low operating current consumption suitable for power-restricted designs.
Maintains stability under capacitive load conditions across the industrial temperature range.

Applications

Battery-powered portable devices requiring low quiescent current
Space-constrained electronic systems utilizing surface-mount packaging
Industrial instrumentation requiring stable voltage references

Procurement Notes

Verify the specific suffix BILT corresponds to the required ±0.5% accuracy grade and reel packaging configuration. Confirm that the SOT-23-3 footprint matches the target PCB layout. Ensure the industrial temperature rating aligns with the operational environment requirements before finalizing procurement specifications.

Selection Notes

Select this component when a precise 1.225V reference is needed with minimal power consumption. The ±0.5% tolerance offers higher precision than standard versions. Consider the SOT-23-3 package size for space-limited applications. Verify compatibility with downstream circuitry regarding the 12 mA maximum current capability.

Part Context

The TS821 series consists of micropower shunt voltage references designed for efficiency and stability. The TS821BILT represents the B-grade variant, distinguished by its tighter ±0.5% initial accuracy compared to standard or A-grade options. This series is part of STMicroelectronics' portfolio for low-power analog signal conditioning.
