The TPS74801-Q1 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 designed 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 allows a solution to be configured that meets the sequencing requirements of FPGAs, DSPs, and other applications with special start-up requirements.
A precision reference and error amplifier delivers 2% accuracy over load, line, temperature, and process. The device is stable with any type of output capacitor greater than or equal to 2.2µF, and is fully specified for TJ = –40°C to +150°C for the new chip, TJ = –40°C to +105°C for the DRC package, and TJ = –40°C to +125°C for the RGW package. The TPS74801-Q1 is offered in a small 3mm × 3mm VSON-10 package, yielding a highly compact, total solution size. The device is also available in a 5mm × 5mm VQFN-20.
