The TPS720xxEVM-307 evaluation module (EVM) assists designers in evaluating the operation and
performance of the TPS720xx low dropout (LDO) linear regulator. This LDO provides up to 350 mA of
output current at a fixed output programmed at the factory. The board features the 1,33-mm
performance of the TPS720xx low dropout (LDO) linear regulator. This LDO provides up to 350 mA of
output current at a fixed output programmed at the factory. The board features the 1,33-mm

Changing components can improve or degrade EVM performance. For example, adding a larger output
capacitor reduces output voltage undershoot but lengthens response time after a load transient event.
