Overview
The TS3312AMR is a micropower series voltage reference IC from STMicroelectronics, providing a fixed output voltage of 1.25 V. It features high initial accuracy with a tolerance of ±0.15% and operates with an ultra-low typical supply current of 3.9 μA at 25 °C. The device supports a maximum input voltage of 5.5 V and delivers up to 5 mA of output current. It is housed in a compact SOT-23-3 package and is specified for operation across a wide temperature range from -40 °C to +125 °C.
Feature Summary
- Micropower consumption with ultra-low operating current
- High initial accuracy for precision applications
- Wide operating temperature range suitable for harsh environments
Applications
- Battery-powered instrumentation systems
- Portable measurement devices
- Data acquisition systems requiring stable reference voltages
Procurement Notes
Verify the specific part marking and datasheet revision against official STMicroelectronics documentation to ensure authenticity. Confirm that the SOT-23-3 package orientation matches your PCB footprint design. Ensure the 1.25 V output voltage aligns with your system requirements before procurement.
Selection Notes
Select this component when a low-cost, low-power voltage reference is required for battery-operated devices. The 1.25 V output is suitable for driving ADCs or DACs where minimal quiescent current is critical. Consider the ±0.15% initial accuracy for applications demanding precise baseline voltage stability without complex calibration.
Part Context
This component belongs to the TS33 family of low-power series voltage references designed by STMicroelectronics. The family includes various fixed output voltages such as 2.048 V, 2.5 V, and 3.3 V, all sharing similar micropower characteristics and packaging options like SOT-23-3 for space-constrained designs.
Replacement Considerations
Check for other members of the TS33 family with different fixed output voltages if 1.25 V is not strictly required. Verify pinout compatibility with alternative SOT-23-3 voltage references from other manufacturers if supply chain constraints exist.
