Overview
The TLV431CLPE3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of 2.5 V to 7 V and provides an adjustable output voltage from 1.24 V to 6 V. The device features an initial accuracy of 0.4% and a maximum temperature coefficient of 138 ppm/°C. It supports a cathode current range from 80 µA to 15 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
- Provides high-precision voltage regulation with 0.4% initial accuracy for stable reference applications
- Operates efficiently at low voltages, supporting input ranges down to 2.5 V
- Designed for wide thermal stability, functioning effectively across extended industrial temperature ranges
Applications
- Precision voltage references in battery-powered equipment
- Programmable output regulators in power supply circuits
- Error amplifiers in switching mode power supplies
Procurement Notes
Verify the specific suffix CLPE3 against official Texas Instruments documentation to confirm the TO-92-3 package and 0.4% accuracy grade. Ensure compatibility with low-voltage operational requirements. Cross-reference datasheet revisions to confirm RoHS compliance status and active lifecycle stage before finalizing procurement decisions.
Selection Notes
Select this component when precise low-voltage referencing is required in compact through-hole designs. The 0.4% accuracy suits applications demanding tighter tolerance than standard 1% variants. Verify that the 15 mA maximum cathode current meets the circuit's sink requirements and that the TO-92-3 footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the TLV431 family of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to higher-voltage counterparts like the TL431, specifically optimized for modern low-power electronics. The device integrates a bandgap reference and error amplifier into a single three-terminal package.
Replacement Considerations
TLV431ACLPRE3 offers similar functionality with 1% accuracy. TLV431BCLP provides 0.5% accuracy in the same package. Verify pinout compatibility and electrical parameter differences before substitution.
