Overview
The TLV431ACLPE3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 6 V and supports a maximum cathode current of 15 mA. The device features an initial accuracy of 1% and a temperature coefficient of 138 ppm/°C. Designed for through-hole mounting, it utilizes a TO-92-3 package. The component functions effectively across an extended operating temperature range from -40°C to +125°C, ensuring stable reference performance in various electronic applications.
Feature Summary
- Provides precise adjustable voltage referencing with high initial accuracy
- Operates efficiently at low voltages suitable for modern portable electronics
- Maintains stability over a wide industrial temperature range
Applications
- Portable equipment power management circuits
- Battery-powered system voltage monitoring
- General-purpose analog signal conditioning
Procurement Notes
Verify the specific suffix 'E3' indicates lead-free compliance and RoHS standards during sourcing. Confirm the TO-92-3 through-hole package availability matches your PCB layout requirements. Ensure the 15 mA current limit aligns with your circuit design constraints before finalizing procurement orders.
Selection Notes
Select this component when low-voltage operation below 7 V is required compared to standard 36 V regulators. The TO-92 package facilitates easy prototyping and manual assembly. Consider the 138 ppm/°C temperature coefficient for applications requiring moderate thermal stability without complex compensation networks.
Part Context
This part belongs to the TLV431 family of low-voltage programmable shunt regulators. It serves as a direct replacement for higher voltage counterparts like the TL431 in low-voltage designs. The series offers improved performance characteristics for battery-operated devices where minimizing quiescent current and maximizing accuracy are critical design priorities.
Replacement Considerations
The TLV431AIDBZR is a documented substitute option available from Texas Instruments. Verify pin compatibility and electrical specifications before implementing any cross-references in existing designs.
