Product Overview: Texas Instruments TLV431CLPR

The Texas Instruments TLV431CLPR is a precision low-voltage shunt voltage reference that offers the flexibility of a programmable voltage reference with the stability and accuracy of a bandgap reference. This device is part of the TLV431 series, which is renowned for its high accuracy, low operational voltage, and ease of use.

The TLV431CLPR operates at a nominal voltage of 1.24 volts but can be set to any value between 1.24 V and 16 V with the use of two external resistors. This feature makes it highly versatile for various applications, including adjustable power supplies, battery-operated equipment, and precision voltage regulation scenarios.

One of the key features of the TLV431CLPR is its low dynamic output impedance, which is a critical parameter for maintaining voltage stability under varying load conditions. This characteristic, along with the device's low operational current, contributes to its robust performance in closed-loop configurations.

The TLV431CLPR is also characterized by its tight voltage tolerance. With an initial accuracy as tight as 1%, the device ensures reliable performance in precision applications. Furthermore, the temperature stability is managed through a specified drift, which maintains the output voltage within a narrow range over the entire industrial temperature range (-40°C to 85°C).

Packaged in a TO-92 form factor, the TLV431CLPR is designed for through-hole mounting, making it suitable for prototyping as well as for commercial production. The device's small footprint allows for a compact design in end products, saving valuable board space.

Safety and reliability are paramount, and the TLV431CLPR addresses these concerns with its inherent thermal stability and a specified maximum output current. These features, combined with Texas Instruments' reputation for high-quality semiconductor products, make the TLV431CLPR a preferred choice for designers seeking a reliable voltage reference solution.

In summary, the TLV431CLPR from Texas Instruments is a highly accurate, programmable shunt voltage reference that offers stability, low power consumption, and versatility for a wide range of applications.
