TL431AIDBZRG4 Description

Short technical summary and product information.

The Texas Instruments TL431AIDBZRG4 is a three-terminal adjustable shunt regulator designed for stable operation over various temperature ranges. Its output voltage can be precisely set between Vref (approximately 2.5V) and 36V using two external resistors.

 

Key electrical characteristics include a reference voltage tolerance of 0.5% at 25°C (B grade), a typical output impedance of 0.2Ω, and a sink current capability ranging from 1mA to 100mA. The device operates from -40°C to 85°C.

 

Packaged in a SOT-23 (DBZ) with 3 pins, this regulator is suitable for applications requiring on-board regulation and adjustable power supplies. Its active output circuitry provides a sharp turn-on characteristic, making it a good replacement for Zener diodes in many designs.
