The TPS7N48 low-dropout (LDO) linear regulator provides an easy-to-use robust power-management design 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. Soft-start is monotonic and designed for powering many different types of processors and application-specific integrated circuits (ASICs). The enable input and power-good output allow easy sequencing with external regulators. This flexibility enables a design to be configured that meets the sequencing requirements of many applications. Field-programmable gate arrays (FPGAs), digital signal processors (DSPs), and other applications with special start-up requirements are some examples that benefit from this flexibility.

A precision reference and error amplifier deliver 2% accuracy. The device is stable with any type of capacitor greater than or equal to 10µF, and is fully specified for TJ = –40°C to +125°C. The TPS7N48 is offered in a small, 2mm × 2mm, WSON-10 package, yielding a highly compact total design size.
