Overview
The TLVH431ILPRE3 is an adjustable precision shunt regulator from Texas Instruments, housed in a TO-92-3 through-hole package. It operates with a maximum reference input voltage of 18 V and supports an adjustable output voltage range up to 18 V. The device features an initial accuracy of 1.5% and a temperature coefficient of 100 PPM/C. It handles a maximum cathode current of 70 mA with a minimum operating current of 100 µA. The component functions within a temperature range of -40°C to +125°C.
Feature Summary
- Provides adjustable precision voltage regulation suitable for low-voltage applications
- Offers high thermal stability with a low temperature coefficient
- Supports wide operating temperature ranges for industrial environments
Applications
- Low-voltage power supply regulation
- Portable equipment power management
- Battery-powered system references
Procurement Notes
Verify the specific suffix PRE3 indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as required by project specifications. Ensure the TO-92-3 through-hole footprint matches the target PCB design constraints. Check for any end-of-life notifications or production changes associated with this specific manufacturer part number before finalizing procurement plans.
Selection Notes
Select this component when a low-cost, through-hole adjustable shunt regulator is required for circuits operating below 18 V. The 1.5% initial accuracy and 100 PPM/C temperature coefficient make it suitable for general-purpose applications where extreme precision is not critical. Consider the 70 mA cathode current limit when designing load requirements.
Part Context
This part belongs to the TLVH431 series of low-voltage adjustable shunt regulators. It serves as a cost-effective alternative to higher-voltage counterparts like the TL431, specifically optimized for systems with lower supply voltages. The TO-92-3 package provides a compact solution for through-hole assembly processes commonly used in consumer electronics and industrial control panels.
Replacement Considerations
TLVH431BPRE3 offers improved 0.5% accuracy. TLVH431QPRE3 provides automotive-grade qualification. Standard TL431 variants support higher voltages up to 36 V but may require different biasing considerations.
