ON Semiconductor TLV431ASNT1 Adjustable Precision Shunt Regulator

The TLV431ASNT1 from ON Semiconductor is a high-performance adjustable precision shunt regulator that offers excellent temperature stability and output current handling capability. Designed to support a wide range of applications, this device is particularly well-suited for adjustable voltage references, isolated feedback circuits, and voltage monitoring in consumer, industrial, and automotive systems.

This versatile component can be programmed from the reference voltage of 1.24V up to 16V with two external resistors. The TLV431ASNT1 features a guaranteed reference accuracy of ±1% at 25°C and ±2% over the entire industrial temperature range of -40°C to +85°C. Its low output noise and low dynamic output impedance ensure a stable and precise voltage regulation, making it ideal for high-performance applications.

The TLV431ASNT1 is capable of sourcing up to 15mA of output current. Despite its high current capacity, it maintains a low operational current of 0.4mA typical, which contributes to the efficiency of the overall system. This shunt regulator operates over a wide range of cathode voltages from -0.2V to 18V and offers excellent transient response, which is critical for applications that experience rapid changes in load.

Encased in a compact SOT-23 package, the TLV431ASNT1 is designed for surface-mount technology, allowing for efficient use of PCB space. Its small footprint and lead (Pb)-free construction make it an environmentally friendly choice for modern electronic designs.
