Test points
The TS6001-2.5V demo board provides an on-board
0.1µF decoupling capacitor at the input. Two pads
are available at the output to accommodate a
capacitive load and a resistive load. The demo board
includes a supply test point with a dedicated ground
test point as well as an output test point with a
dedicated ground test point.
The TS6001-2.5V is available in a PCB-space saving
3-lead SOT23 surface-mount package.

TS6001 Voltage Reference Demo Board
The demo board provides an on-board 0.1µF
decoupling capacitor at the VIN input. Two pads are
available at the output to accommodate a capacitive
load and a resistive load as needed.
Required Equipment
TS6001DB demo board
A DC Power Supply, Single, an HP Model
HP6624A or equivalent
A digital voltmeter, an HP34410A or equivalent
A digital ammeter, an HP34410A or equivalent
To evaluate the TS6001 voltage reference, the
following steps are to be performed:
1) Before connecting the DC power supply to the
demo board, turn on the power supply and set
the DC voltage to 5V and then turn it off.
2) Connect the DC power supply positive terminal to
the negative terminal of the digital ammeter.
Then, connect the positive terminal of the
ammeter to the test point VIN and the negative
terminal of the DC power supply to the adjacent
test point GND.
6) The input voltage VIN can vary from VOUT +
0.2V to 12.6V as needed. Please refer to the
TS6001 product datasheet “Electrical
Characteristics” section for more information.
Note: In order to add a Kelvin connection to the
output test point VOUT, connect the positive terminal
of a DVM to VOUT and the negative terminal to GND.
Then, place a resistor and/or capacitor on pads R1
and/or pads C1, respectively. For an accurate VOUT
measurement, always connect the positive terminal of
the DVM to the VOUT test point.
If additional loading is needed on the output VOUT, a
wire can be soldered on pads R1 and C1. Then, a
load can be connected to the other end of the wire.
Make sure the load is connected to the ground on the

4) An optional load resistor ≥ 5kΩ and capacitor up
to 2200pF can be soldered on the board. Solder
the resistor on pads R1 and the capacitor on
pads C1. If a load is not desired, leave these
pads open and proceed to step 5.
5) Turn on the power supply and check that the
digital voltmeter is reading an output voltage
within ±0.2% of 2.5V and the digital ammeter is
reading a supply current less than 35µA.

3) Connect the positive terminal of the digital
voltmeter to test point VOUT and the negative
terminal to the adjacent test point GND.
