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 electrical performance. The TS6001
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.

Electrical and thermal stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at these or any other condition beyond those indicated in the operational sections
of the specifications is not implied. Exposure to any absolute maximum rating conditions for extended periods may affect device reliability and
lifetime.

Note 1:
All devices are 100% production tested at T
A
= +25°C and are guaranteed by characterization for T
A
= T
MIN
to T
MAX
, as specified.
Note 2:
Temperature Coefficient is measured by the “box” method; i.e., the maximum
∆V
OUT
is divided by the maximum
∆T.
Note 3:
Dropout voltage is the minimum input voltage at which V
OUT
changes
≤0.2%
from V
OUT
at V
IN
= 5.0V.
Note 4:
Temperature hysteresis is defined as the change in the +25°C output voltage before and after cycling the device from +25°C to T
MIN
to
+25°C and from +25°C to T
MAX
to +25°C.
Note 5:
Reference long-term drift or stability listed in the table is an intermediate result of a 1000-hour evaluation. Soldered onto a printed
circuit board (pcb), voltage references exhibit more drift early in the evaluation because of assembly-induced differential stresses
between the package and the pcb.
Note 6:
Not production tested; guaranteed by design.
