TS3431- Precision 1.24V Programmable Shunt Voltage Reference
Offering high precision and low consumption within an industrial temperature range, the TS3431 programmable shunt voltage refer ence targets SMPS applications, and industrial or automotive applications.
Low Consumption, High Precision
An ideal general-purpose programmable voltage reference, the TS3431 offers an extended emperature range, adjustable output voltage (1.24 to 24V), low current consumption (0.4mA to 100mA), high precision and small surface-mounted package. The TS3431 is available in the space-saving SOT23-3L package and the standard TO92, 3-pin package. It is also pin-topin compatible with the industry standard TL431.
The TS3431 has a low operating current of 0.4mA, which is ideal for switch-mode power supplies (SMPS) requiring low standby current for power savings. The TS3431’s low current consumption reduces the secondary-side current allowing the reduction of the overall power consumption for the entire power supply. This environment-friendly feature is increasingly important, especially as many power supplies are continuously plugged in, with or without a load.
