TS6001-2.5V Voltage Reference Demo Board FEATURES DESCRIPTION The demo board for the TS6001-2.5V is a completely 2 output pads for output loading assembled and tested circuit board that can be used Fully Assembled and Tested for evaluating the TS6001-2.5V voltage reference. 2in x 1in 2-layer circuit board The TS6001-2.5V demo board provides an on-board COMPONENT LIST 0.1F decoupling capacitor at the input. Two pads are available at the output to accommodate a capacitive load and a resistive load. The demo board DESIGNATION QTY DESCRIPTION C2 1 0.1F 10% includes a supply test point with a dedicated ground capacitors (0805) test point as well as an output test point with a U1 1 TS6001AIG325 dedicated ground test point. Voltage Reference VIN, VOUT, GND 4 Test points The TS6001-2.5V is available in a PCB-space saving 3-lead SOT23 surface-mount package.
