TLV431BCLPR

Overview

The TLV431BCLPR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply 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 temperature coefficient of 138 PPM/C. It supports a maximum cathode current of 15 mA with a minimum operating current of 80 uA. The component functions across an extended temperature range from -40°C to +125°C and is housed in a TO-92-3 through-hole package.

Feature Summary

• Provides high-precision voltage regulation with 0.5% initial accuracy for stable reference applications
• Operates at low voltages with an adjustable output range extending up to 6 V
• Designed for wide thermal stability, functioning reliably from -40°C to +125°C

Applications

• Low-voltage power supply feedback loops
• Precision voltage references in battery-powered devices
• Comparator circuits requiring accurate threshold levels

Procurement Notes

Verify the specific suffix CLPR indicates the reel or cut-tape packaging configuration as listed in distributor catalogs. Confirm RoHS compliance status through official Texas Instruments documentation prior to integration. Ensure the procurement channel sources genuine components to maintain the specified 0.5% accuracy and thermal performance characteristics defined in the datasheet.

Selection Notes

Select this component when low-voltage operation below 7 V is required alongside high precision. The TO-92-3 package suits through-hole designs needing robust mechanical mounting. Consider the 15 mA cathode current limit for load requirements. The extended temperature range makes it suitable for industrial environments where standard commercial grade parts may fail.

Part Context

This part belongs to the TLV431 family of low-voltage adjustable shunt regulators. It serves as a modern alternative to traditional Zener diodes, offering superior accuracy and lower dynamic impedance. The TLV431 series is widely used in power management ICs for providing stable reference voltages in switching converters and linear regulators.
