DESCRIPTION
The TS6001 is a 3-terminal, series-mode 2.5-V
precision voltage reference and is a pin-for-pin,
identical to the MAX6025 voltage reference with
improved
consumes only 31μA of supply current at no-load,
exhibits an initial output voltage accuracy of less than
0.08%, and a low output voltage temperature
coefficient of 7ppm/°C. In addition, the TS6001’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 TS6001 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 TS6001’s small form factor and low supply
current operation all combine to make it an ideal
choice in low-power, precision applications.
The TS6001 is fully specified over the -40°C to +85°C
temperature range and is available in a 3-pin SOT23
package.
