Texas Instruments TPS74701 | Demoboard TPS74701EVM-177

Beschreibung

The Texas Instruments TPS74x01EVM-177 evaluation module uses the TPS74701 or TPS74801 low-dropout linear regulator device. These regulators require a low-power bias voltage, VBIAS, and a power input voltage, VIN. These two regulators are capable of providing output voltages down to 0.8 V 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 and TPS74801 can provide up to 0.5 A and 1.5 A of output current, respectively, and each has a soft start (SS) pin which allows the user to set the linear ramp rate for the output voltage at start-up. The purpose of the EVM is to facilitate evaluation of the TPS74x01 devices.
