General Description

The TPS742 series of low-dropout (LDO) linear regulators provide an easy-to-use, robust powermanagement 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.
