TSM1014AID

Overview

The TSM1014AID is a series voltage reference IC manufactured by STMicroelectronics, housed in an 8-SOIC package. It provides a fixed output voltage of 1.25V with a tolerance of ±0.5%. The device operates within an input voltage range of 4.5V to 28V and supports a supply current of up to 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

• Incorporates a high-stability series bandgap voltage reference architecture
• Provides precise fixed output voltage regulation with low tolerance
• Features integrated operational amplifiers for feedback control applications

Applications

• Secondary side switching-mode power supply control
• AC/DC converter auxiliary power management
• Voltage and current controller circuits in isolated power supplies

Procurement Notes

Verify the specific suffix (e.g., DT vs TR) against the required packaging format, as the base part number may correspond to different reel or cut-tape options. Confirm the exact operating temperature grade and package width specifications match the design constraints before finalizing the order.

Selection Notes

Select this component when a stable 1.25V reference is required for secondary-side regulation in flyback or forward converters. Ensure the input voltage remains within the 4.5V to 28V range and that the thermal environment stays within the specified -40°C to 105°C limits for reliable operation.

Part Context

This device belongs to the TSM101 family of voltage and current controllers from STMicroelectronics. These ICs are designed to integrate a voltage reference with operational amplifiers and current sources, facilitating closed-loop control in switch-mode power supplies via optocoupler feedback to primary-side PWM controllers.
