TLV431BLPG

Overview

The TLV431BLPG is a low voltage precision adjustable shunt regulator from onsemi, housed in a TO-92 (TO-226) package. It features an adjustable output voltage range of 1.24 V to 16 V with a reference tolerance of ±0.5%. The device supports a maximum cathode current of 20 mA and operates within a temperature range of -40°C to +85°C. It is designed for surface mount or through-hole applications as a shunt voltage reference.

Feature Summary

• Adjustable output voltage programmable between 1.24 V and 16 V
• High initial accuracy with ±0.5% reference tolerance
• Low voltage operation suitable for battery-powered systems

Applications

• Precision voltage references in power supplies
• Programmable output regulators
• Battery-operated equipment requiring stable reference voltages

Procurement Notes

Verify component status before procurement as the TLV431BLPG may be subject to obsolescence notices. Confirm package type compatibility and thermal requirements against design specifications. Ensure sourcing channels provide genuine onsemi products to maintain reliability standards for critical voltage reference applications.

Selection Notes

Select this component when a low-voltage, high-precision shunt regulator is required. The ±0.5% tolerance suits applications demanding tighter accuracy than standard A-series devices. Consider the TO-92 package for through-hole designs where space allows, ensuring input voltage limits and current capabilities align with circuit demands.

Part Context

Part of the TLV431 series, which offers low-cost, low-voltage alternatives to traditional TL431 regulators. This specific BLPG variant provides improved accuracy over the standard A-series while maintaining compatibility with common shunt regulator topologies. It serves as a direct replacement for many legacy adjustable reference designs in consumer and industrial electronics.

Replacement Considerations

TLV431BSPR2G is an active alternative in the same family with similar electrical characteristics.
