LDO Regulator with Soft Start and Tracking
The devices described here are tailored to fit the needs of modern DSPs, processors and FPGAs that require low supply voltages at relatively high currents, plus the capability of supply voltage ramp-up and sequencing in a defined manner. The latter two requirements are not easily solved using discrete components. The TPS74x01 family fits the bill.
At the time of writing the family consists of three parts, called TPS74201 (1.5 A with soft-start), TPS74301 (1.5 A with tracking) and TPS74401 (
