TL431IDBZR Description

Short technical summary and product information.

The TL431IDBZR is an adjustable precision shunt regulator from Texas Instruments, designed for stable operation across various temperature ranges. This three-terminal device allows the output voltage to be set anywhere between approximately 2.5V (Vref) and 36V using two external resistors.

Key electrical characteristics include a typical output impedance of 0.2Ω and a sink current capability ranging from 1mA to 100mA. The reference voltage tolerance is 0.5% at 25°C for the B grade. The device operates reliably within a temperature range of -40°C to 85°C.

Packaged in a compact SOT-23 (DBZ) case with 3 pins, the TL431IDBZR is suitable for applications requiring precise voltage regulation. Its active output circuitry provides a sharp turn-on characteristic, making it a versatile replacement for Zener diodes in on-board regulation and adjustable power supply designs.
