TL431ILPR Description

Short technical summary and product information.

The TL431ILPR from Texas Instruments is a three-terminal adjustable shunt regulator designed for applications requiring precise voltage regulation. It offers a wide adjustable output voltage range, from its reference voltage (approximately 2.5V) up to 36V, set using two external resistors.

Key electrical characteristics include a typical reference voltage tolerance of 0.5% at 25°C for the B grade, with other grades offering 1% and 2%. The device operates reliably over a temperature range of -40°C to 125°C. It features a low output noise and a typical output impedance of 0.2Ω, making it a suitable replacement for Zener diodes in various power supply designs.

Packaged in a TO-92 (LP) through-hole package, the TL431ILPR is suitable for on-board regulation, adjustable power supplies, and switching power supplies. It has a sink-current capability ranging from 1mA to 100mA and is supplied in bulk packaging with 1000 units per package.
