Overview
The TLV431AILPRE3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 1.24 V to 6 V with an initial accuracy of ±1%. The device supports a maximum cathode current of 15 mA and requires a minimum operating current of 80 µA. It features a temperature coefficient of 138 PPM/°C and functions across a temperature range of -40°C to +85°C. Housed in a TO-92-3 through-hole package, it serves as a compact reference solution for power management applications.
Feature Summary
- Adjustable output voltage capability ranging from 1.24 V to 6 V via external resistors
- High initial accuracy of ±1% ensures precise voltage referencing
- Low minimum operating current of 80 µA optimizes efficiency in battery-powered designs
Applications
- Secondary regulation in switch-mode power supplies
- Battery-operated equipment requiring stable voltage references
- Data acquisition systems needing precise analog references
Procurement Notes
Verify the specific suffix PRE3 indicates tape-and-reel packaging compatible with automated assembly processes. Confirm RoHS compliance status and ensure the TO-92-3 through-hole package matches the target PCB footprint requirements. Check for any recent product change notices regarding manufacturing location or material composition updates.
Selection Notes
Select this component when a low-voltage adjustable reference under 6 V is required with high accuracy. The TO-92-3 package suits through-hole designs where space constraints are less critical than surface-mount alternatives. Ensure the application current does not exceed the 15 mA maximum cathode current rating while maintaining stability above the 80 µA minimum threshold.
Part Context
This part belongs to the TLV431 family of low-voltage adjustable shunt regulators. It offers improved performance over standard TL431 devices by supporting lower input voltages and reduced operating currents. The A-grade variant provides tighter tolerance specifications suitable for precision instrumentation and regulated power supply feedback loops.
Replacement Considerations
Direct pin-compatible substitutes include the TLV431ACLPR and TLV431AIDBVT. Verify that alternative packages match the installation style and electrical characteristics such as initial accuracy and temperature coefficient before substitution.
