DESCRIPTION
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 two-
terminal 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.
