TPS74801DRCR Low-Dropout Linear Regulator: Pinout, Datasheet

The TPS74801DRCR low-dropout (LDO) linear regulator is a simple and reliable power management solution for a wide range of applications. User-programmable soft-start reduces capacitive inrush current on startup, minimizing stress on the input power supply. The soft-start is monotonic and suitable for powering a wide range of processors and ASICs. The enable input and power good output make it simple to sequence with external regulators. Because of this comprehensive flexibility, the user can create a solution that matches the sequencing needs of FPGAs, DSPs, and other applications with unique start-up requirements.
