Keywords:stmicroelectronics? ts842 1.2? ts824 2.5? shunt voltage reference?

The TS824-1.2 and TS824-2.5 shunt voltage references from STMicroelectronics has a temperature coefficient of 500ppm/0C, and are claimed to stabilize with capacitive loads, which is useful for power supplies, battery-powered equipment, computers, instrumentation, data acquisition systems, and power management circuits.

The TS824-1.2 provides a 1.225V output and the TS824-2.5 a 2.5V output, making them suitable for battery-powered equipment where power conservation is critical. The TS824-1.2 draws 455A, while the TS824-2.5 draws 605A, both at 250C.

The devices are available in different precisions: 11 percent for TS824-1.2 and 10.5 percent or 11 percent for the TS824-2.5. Both are packaged in SOT-23 casings.
