Overview
The TLVH431BCLPE3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 20 V, providing an adjustable output voltage from 1.24 V to 18 V via external resistors. The device features an initial accuracy of 0.5% and a temperature coefficient of 138 ppm/°C. It supports a cathode current range from 80 µA to 80 mA and functions reliably across an operating temperature range of -40°C to +125°C. The component is housed in a TO-92-3 through-hole package.
Feature Summary
- Adjustable output voltage capability using external resistor dividers
- High precision with 0.5% initial accuracy specification
- Wide operating temperature range for industrial environments
Applications
- Battery chargers
- Switch mode power supplies
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'E3' against the manufacturer's latest documentation to confirm compliance status and material composition details. Confirm that the TO-92-3 through-hole package matches the target PCB footprint requirements. Ensure the 0.5% accuracy grade meets the design specifications for the intended application circuit.
Selection Notes
Select this component when a through-hole adjustable reference is required for space-unconstrained designs. The TO-92-3 package facilitates manual assembly or wave soldering processes. Consider the 80 mA sink current capability for driving loads directly without additional buffering stages in simple regulation circuits.
Part Context
This part belongs to the TLVH431B series of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to bandgap references in applications requiring programmable voltage thresholds. The device integrates a temperature-compensated zener diode structure to maintain stability over the specified wide temperature range.
Replacement Considerations
Check for direct pin-compatible alternatives such as the TLVH431BCLP if the E3 suffix denotes a specific environmental variant. Verify electrical parameter equivalence for critical design margins before substitution.
