The TPS74701EVM-177 is an evaluation for TPS74701 low dropout linear regulator. This regulator require a low power bias voltage, VBIAS, and a power input voltage, VIN. The TPS74401 is capable of providing output voltages down to 0.8V and have an integrated supervisory circuit with open drain output that goes to high impedance when the output voltage reaches regulation (power good or PG). The TPS74701 can provide up to 1.5A and 3.0A dc current, respectively, and have a SS pin which allows the user to set the output voltage's linear ramp rate. The goal of the evaluation module is to facilitate evaluation of the TPS74x01 ICs. The TPS74701 low dropout linear regulator provides an easy to use, robust power management solution for a wide variety of applications. User programmable soft start minimizes stress on the input power source by reducing capacitive inrush current on start up. The soft start is monotonic and well suited for powering many different types of processors and ASICs.
