3 EVM Setup
This section describes how to properly connect and setup the TPS715EVM-074, including the jumpers and
connectors on the EVM board. See
3.1 Jumper Connections
3.1.1 J11-14: Output Voltage Select
Connect a shunt across the pins to set the output voltage.
3.2 Test Points
Table 3-2
lists the test points for the TPS715EVM-074.
3.3 Soldering Guidelines
To avoid damaging the LDO, use a hot-air system for any solder rework to modify the EVM for the purpose of
repair or other application reasons.
4 Equipment Connection and Operation
Connect test equipment as described in this section and follow the listed steps to properly take measurements.
1. Configure the onboard shunts to set the main output voltage VOUT
2. Verify that the input voltage power supply is set from 0 V to 24 V
3. Connect the anode of the power supply to J1 (VIN) and the cathode to J2 (GND)
4. Connect the anode of the load for the output to J3 and the cathode to J4
5. Turn on the power supply
6. Vary VIN and the load as necessary for testing purposes
