Description
The TS431 is a low-voltage, three-terminal, programmable shunt voltage reference. The output voltage can be set to any value between Vref (1.24V) and 6V with two external resistors. The TS431 is able to operate at a lower voltage (1.24V) and lower cathode current than the widely used TL431 and TL1431 shunt voltage reference. When driving an optocoupler, the TS431 is particularly useful for regulating 3.3V switching power supplies.

1 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings
- T junction=150°C, Tamb=25°C with
Table 2. Operating conditions
2 Electrical characteristics
Table 3. T amb = 25°C (unless otherwise specified)
- Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation and by design.
- Δ Vref is defined as the difference between the maximum and minimum values obtained over the full temperature range.
ΔVref = Vref max. - Vref min.
3 Package mechanical data
In order to meet environmental requirements, STMicroelectronics offers these devices in ECOPACK® packages. These packages have a Lead-free second level interconnect. The category of second level interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. ECOPACK is an STMicroelectronics trademark. ECOPACK specifications are available at: www.st.com
