Single output LDO, 3.0A, adjustable (0.8 to 3.3V), fast transient response, programmable soft start 'TPS74401'
The TPS74401 low dropout (LDO) linear regulator is an easy-to-use and robust power management solution for a wide range of applications. The soft start is user-programmable, allowing for a reduction in capacitive inrush current during startup, minimizing stress on the input power supply. The soft start is monotonic and suitable for powering many types of processors and application-specific integrated circuits (ASICs). With the enable input and power good output, sequencing with external regulators can be easily performed. This high flexibility allows for the creation of solutions that meet the sequencing control requirements for applications such as FPGAs, DSPs, and other special startup conditions. **Features** - Input voltage range: 1.1V to 5.5V - 1% accuracy across the entire input voltage range, all loads, and all temperature ranges - Supports low input voltage of 0.9V with an external bias supply - Adjustable output: 0.8V to 3.6V - Ultra-low dropout: 115mV at 3.0A (typical) *For more details, please contact us.*
