TL431IPK Description

Short technical summary and product information.

The TL431IPK is a three-terminal adjustable shunt regulator from Texas Instruments, designed for applications requiring precise voltage regulation. It allows the output voltage to be set anywhere between its reference voltage (approximately 2.5V) and 36V using two external resistors. This device features a typical output impedance of 0.2Ω and a sink current capability ranging from 1mA to 100mA.

 

With a reference voltage tolerance of 0.5% at 25°C (for the B grade), the TL431IPK ensures stable performance. It operates across a temperature range of -40°C to 85°C, making it suitable for various environmental conditions. The active output circuitry provides a sharp turn-on characteristic, serving as an effective replacement for Zener diodes in applications like on-board regulation, adjustable power supplies, and switching power supplies.

 

The TL431IPK is supplied in a SOT-89 surface-mount package, with a standard package quantity of 1000 units on tape and reel.
