Overview
The TL431LB-TP is a programmable precision shunt voltage reference manufactured by Micro Commercial Components (MCC). It operates within a cathode voltage range of 2.495V to 36V and provides an adjustable output voltage. The device features a typical sink current capability of 100mA with a minimum operating current of 500µA. It exhibits a tolerance of ±0.5% and a temperature coefficient of 50ppm/°C. Designed for surface-mount applications, it utilizes the SOT-23 package and supports an extended operating temperature range from -40°C to 125°C.
Feature Summary
- Provides precise programmable reference voltage functionality via external resistors
- Delivers high stability across wide industrial temperature ranges
- Offers low dynamic output impedance for accurate regulation
Applications
- Switching power supply feedback loops
- Portable equipment power management
- Parallel linear regulators
- Voltage monitoring circuits
Procurement Notes
Verify component authenticity through authorized MCC distributors or certified suppliers. Confirm datasheet revisions and RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain package integrity during assembly processes.
Selection Notes
Select this component when precise voltage referencing in compact surface-mount designs is required. The SOT-23 form factor suits space-constrained layouts. Evaluate thermal performance against system dissipation limits. Verify that the ±0.5% tolerance meets circuit accuracy specifications compared to standard grades.
Part Context
This part belongs to the TL431 family of three-terminal adjustable shunt regulators. These devices serve as versatile alternatives to Zener diodes in power management systems. The series is widely utilized for its reliability and cost-effectiveness in consumer electronics and industrial control applications requiring stable reference potentials.
Replacement Considerations
Compatible substitutes include TL431ACZ-TP and TL431BCZ-TP from the same manufacturer. Cross-vendor equivalents such as the LM431BIMX/NOPB offer similar electrical characteristics. Verify pinout compatibility and thermal resistance values before implementing any alternative components.
