TLV431BSN1T1G

Overview

The onsemi TLV431BSN1T1G is a low voltage precision adjustable shunt regulator housed in an SOT-23-3 surface-mount package. It features a programmable output voltage range from 1.24 V to 16 V with a reference accuracy of ±0.5% at 25 °C and ±1.0% over the industrial temperature range of -40 °C to 85 °C. The device exhibits a sharp low current turn-on characteristic and maintains a low dynamic impedance of 0.25 Ω across an operating cathode current range of 0.1 mA to 20 mA.

Feature Summary

Programmable output voltage range spanning 1.24 V to 16 V
High reference accuracy of ±0.5% at 25 °C
Sharp low current turn-on characteristic
Low dynamic output impedance of 0.25 Ω

Applications

Error amplifier for isolated low output voltage switching power supplies
Adjustable voltage or current linear and switching power supplies
Voltage monitoring circuits
Current source and sink circuits
Precision references for analog and digital circuits

Procurement Notes

Verify the specific suffix SN1T1G corresponds to the SOT-23-3 package and tape & reel shipping configuration. Confirm that the B series designation aligns with the required ±0.5% initial accuracy specifications. Ensure the operating environment remains within the specified -40 °C to 85 °C temperature range for guaranteed performance parameters.

Selection Notes

Select this component when a precise, low-voltage adjustable reference is required in space-constrained designs. The SOT-23-3 package offers a micro-miniature footprint suitable for surface mount applications. Consider the ±0.5% accuracy tolerance if tighter regulation than the A series is necessary, while ensuring the circuit design accommodates the minimum cathode current requirements for stable regulation.

Part Context

This device belongs to the TLV431 family of low voltage precision adjustable shunt regulators manufactured by onsemi. The family includes variants with different accuracy grades (A, B, C) and packaging options such as TO-92-3 and TSOP-5. The TLV431 series serves as a direct replacement for zener diodes in applications demanding higher precision and stability over temperature variations.
