The TSM6025 is a 3-terminal, series-mode 2.5-V precision voltage reference and is a pin-for-pin, alternate source for the MAX6025 voltage reference. Like the MAX6025, the TSM6025 consumes only 27μA of supply current at no-load, exhibits an initial output voltage accuracy of less than 0.2%, and a low output voltage temperature coefficient of 15ppm/°C. In addition, the TSM6025’s output stage is stable for all capacitive loads to 2200pF and is capable of sinking and sourcing load currents up to 500μA. Since the TSM6025 is a series-mode voltage reference, its supply current is not affected by changes in the applied supply voltage unlike twoterminal shunt-mode references that require an external resistor. The TSM6025’s small form factor and low supply current operation combine to make it an ideal choice in low-power, precision applications. The TSM6025 is fully specified over the -40°C to +85°C temperature range and is available in a 3-pin SOT23 package.
