TLV431CLP

Overview

The TLV431CLP is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of up to 7 V and provides an adjustable output voltage from 1.24 V to 6 V. The device features an initial accuracy of 0.5% and a maximum temperature coefficient of 138 PPM/C. It supports a maximum shunt current of 15 mA and functions reliably across a temperature range of -40°C to +125°C. Housed in a TO-92-3 through-hole package, it serves as a cost-effective reference solution for low-voltage applications.

Feature Summary

• Provides precise voltage regulation with 0.5% initial accuracy
• Operates efficiently at low voltages down to 1.24 V
• Designed for wide industrial temperature stability

Applications

• Low-voltage battery-powered equipment monitoring
• Portable consumer electronics power management
• Industrial control system voltage references

Procurement Notes

Verify the specific suffix 'CLP' corresponds to the TO-92-3 through-hole package variant. Confirm that the 0.5% accuracy grade meets design requirements, as other grades like 'A' or 'B' may offer different tolerances. Ensure the 7 V maximum input voltage constraint aligns with the target circuit supply rails to prevent device damage during operation.

Selection Notes

Select this component when a low-voltage adjustable reference is required in a through-hole format. The 15 mA current capability suits moderate load applications, while the 0.5% accuracy ensures stable regulation. Consider thermal management if operating near the upper temperature limit, and verify that the 1.24 V minimum output voltage fits the feedback network design constraints.

Part Context

This part belongs to the TLV431 family of low-voltage shunt regulators, distinct from the standard TL431 series which supports higher voltages up to 36 V. The TLV431 series is optimized for modern low-power portable devices where supply voltages are typically below 5 V. It offers similar functionality to the TL431 but with enhanced performance characteristics for low-voltage environments.

Replacement Considerations

The TLV431ACLPR is a surface-mount alternative with similar low-voltage specifications. For through-hole replacements, verify pin compatibility with the TO-92-3 package. Other variants within the TLV431 family may differ in accuracy grades or packaging styles.
