TSM1014AIDT

Overview

The TSM1014AIDT is a series voltage reference integrated circuit manufactured by STMicroelectronics, housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 1.25V with a precision tolerance of ±0.5%. The device operates within an input voltage range of 4.5V to 28V and supports a maximum supply current of 50mA. It delivers a maximum output current of 2.5mA and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

High-precision series bandgap voltage reference architecture
Fixed 1.25V output with tight ±0.5% tolerance
Integrated operational amplifiers for feedback control

Applications

Secondary side switch-mode power supply control
AC/DC converter auxiliary power management
Isolated output regulation circuits

Procurement Notes

Verify the specific suffix 'A' indicates the ±0.5% tolerance variant distinct from standard versions. Confirm the 8-SOIC package dimensions match the design footprint. Ensure the 28V maximum input rating aligns with the system's peak supply voltage. Check RoHS3 compliance status for regulatory requirements. Validate the 50mA supply current limit against the total board power budget.

Selection Notes

Select this component when high accuracy is required for secondary-side regulation in isolated converters. The ±0.5% tolerance offers better precision than standard 1% variants. The integrated op-amps simplify feedback loop design compared to discrete references. Consider the 2.5mA output current capability for driving optocouplers directly. Evaluate the wide operating temperature range for industrial or automotive environments.

Part Context

This part belongs to the TSM101 family of voltage and current controllers designed for flyback and forward converter topologies. It integrates a stable reference with dual operational amplifiers to manage both voltage and current loops. The family includes variants with different tolerances and output currents to suit various power levels.
