TPS74201KTWTG3
1.5A超LDO ,可编程软启动 1.5A Ultra-LDO with Programmable Soft-Start
DESCRIPON
The TPS74201 low-dropout LDO linear regulator provides an easy-to-use robust power management
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. The enable input and power-good output allow easy sequencing with external regulators. This complete flexibility permits the user to configure a solution that will meet the sequencing requirements of FPGAs, DSPs, and other applications with special start-up requirements.
