ISL71010BM50EV1Z 2. Functional Description
2.3 Quick Start Guide
(1) Gather the external supply and equipment needed to operate the board:
(a) 7V to 30V DC power supply.
(b) Precision voltmeter (Agilent 3458A digital multimeter or equivalent).
(2) Attach the evaluation board to a DC power supply at test points TP1 and TP2 labeled VIN and GND as shown
in Figure 2 . Attach the positive terminal at VIN (TP1) and the negative terminal at GND. The supply should
be capable of delivering 7V to 30V and 100mA of current.
(3) Connect a precision voltmeter at test points TP3 and TP4 labeled VOUT and GND as indicated in Figure 2 .
(4) Set the supply voltage to 10V.
(5) Turn the DC power supply ON. The voltmeter should read 5.0V ±0.05%.
(6) Change the DC power supply voltage to 20V. The voltmeter should continue to read 5.0V.
(7) Vary the DC power supply voltage over the range of 7V to 30V and the voltmeter should continue to read
5.0V.
(8) Performance at different resistive loads can be evaluated by changing R

with different resistor values.
