1 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

BIAS

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

and 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.
