Quick Start Guide

1. Configure input and output capacitance using jumpers.
2. Place Enable jumper in the enable position.
3. Connect a +5V power supply between IN and GND terminals (ensure it is turned off).
4. Connect a load to OUT and GND terminals.
5. Turn on the power supply.
6. Observe the load current to ensure it stops increasing after reaching a certain level, indicating current limiting functionality.

FAQ

QUICK START GUIDE

1. Insert jumpers to configure the input capacitance and output capacitance as described in the Application Information sections of the device datasheet.
2. Place the Enable jumper in the enable position.
3. Connect a +5V power supply between the IN and GND terminals. Make sure the power supply is turned off.
4. Connect an adjustable current or resistive load to the OUT and GND terminals.
5. Turn on the power supply.
6. Increase the load current and observe that the load current will stop increasing after reaching a certain level. That is an indication that the device is limiting the load current.
