Description
General part information
TPS74301 Series
The TPS743 low-dropout (LDO) linear regulator provides an easy-to-use robust power management design for a wide variety of applications. The TRACK pin allows the output to track an external supply. This feature is useful in minimizing the stress on ESD structures that are present between the CORE and I/O power pins of many processors. The enable input and power-good output allow easy sequencing with external regulators. This complete flexibility allows the user to configure a solution that meets the sequencing requirements of FPGAs, DSPs, and other applications with special start-up requirements.
A precision reference and error amplifier deliver 1% accuracy over load, line, temperature, and process. The device is stable with any type of capacitor greater than or equal to 2.2µF. Each LDO is stable with low-cost ceramic output capacitors and the family is fully specified from –40°C to 125°C.
