Automotive 500-mA, low-VIN (0.8-V), adjustable ultra-low-dropout voltage regulator with power good

The TPS74701-Q1 low-dropout (LDO) linear regulator

provides an easy-to-use, robust power management solution for a wide variety of

applications. The user-programmable soft-start minimizes stress on the input power

source by reducing capacitive inrush current and the monotonic start-up is designed

for powering many different types of processors and ASICs. The enable input and

power-good output allow easy sequencing with external regulators, allowing a

solution to be configured that meets the sequencing requirements for a wide range of

applications with special start-up requirements.

A precision reference and error amplifier deliver

0.95% accuracy over load, line, temperature, and process. The device is stable with

any type of capacitor greater than or equal to 2.2 µF, and is fully specified per

AEC-Q100.
