Introduction
The TPS740xxDGKEVM-722 evaluation module helps designers evaluate the operation and performance
of the TPS740xx low-voltage, low-dropout regulator in an 8-pin power MSOP-8 package. This particular
EVM configuration contains a low-voltage, low-dropout (LDO), 1.5-A voltage regulator with dual input
voltages with input voltage range of 1.2 V to 5.5 V and input V

range of 3 V to 5.5 V. Two
TPS740xxDGK EVMs are available: one with an adjustable output voltage and one with a fixed voltage of
1.2 V. The output voltage of TPS74001DGKEVM is adjustable and is configured with external resistors, R

, to 1.5 V. The output voltage for this part can be adjusted to be between 0.9 V and 4 V. The output
voltage of TPS74012DGKEVM is fixed to 1.2 V, set by resistors internal to the integrated circuit (IC), and
cannot be modified. The TPS740xx is also available in a 5-pin Jr S-Pak package, which has its own
orderable evaluation module, TPS74001DPTEVM-713 or TPS74012DPTEVM-713. The TPS740xx is ideal
for powering microprocessors.
