Texas Instruments Precision Shunt Voltage Reference 5V TO-226AA-3

The Texas Instruments 5V Precision Shunt Voltage Reference is a monolithic integrated circuit operating as a low-temperature coefficient 5V Zener diode with a dynamic impedance of 0.6Ω. This precision shunt regulator provides a stable 5V reference, making it suitable for a wide range of demanding electronic applications.

A key feature of this device is its third terminal, which allows the reference voltage and temperature coefficient to be easily trimmed. This ensures optimal performance and minimum temperature drift in sensitive circuits. The device boasts a low-temperature coefficient and offers an initial tolerance of ±1%. Furthermore, it features fast turn-on capabilities, allowing for quick stabilisation in power circuits.

Housed in a robust TO-226AA package with 3 pins, this voltage reference is designed for reliable through-hole mounting. It operates effectively within a temperature range of 0°C to 70°C, ensuring consistent performance under standard environmental conditions. With compact dimensions of 43 mm in height, 33 mm in width, and 15 mm in depth, it is well-suited for space-constrained designs. Whether you are designing power management systems or precision measurement equipment, this shunt voltage reference delivers the accuracy and stability required.
