The Texas Instruments TPS7A74EVM-068 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS7A74 LDO voltage regulator. As shown in Table 1-1, the TPS7A74EVM-068 contains one TPS7A74 LDO voltage regulator in the DSD package. An optional load transient circuit is also included to assist the user with high-speed load transient testing. To simplify current measurements, an input current loop is included.

This section describes the jumpers and connectors on the EVM, and how to properly connect, set up, and use the TPS7A74EVM-068. Section 2.1 and Section 2.3 describe the test setup and operation for the TPS7A74 LDO. Section 2.2 and Section 2.4 describe the test setup and operation of the optional load transient circuit.
VIN and GND are the connection terminals for the input supply. The VIN terminal is the positive connection, and the GND terminal is the negative (that is, ground) connection.
BIAS and GND are the connection terminals for the bias supply. The BIAS terminal is the positive connection, and the GND terminal is the negative (that is, ground) connection.
