Texas Instruments TPS74801/TPS74801-Q1 LDO Linear Regulators
Texas Instruments TPS74801/TPS74801-Q1 Low-Dropout (LDO) Linear Regulators offer an easy-to-use, robust power management solution for a wide variety of applications. These linear regulators provide user-programmable soft-start that minimizes stress on the input power source by reducing capacitive inrush current on start-up. The monotonic start-up is designed to power many types of processors and Application-Specific Integrated Circuits (ASICs). The TPS74801/TPS74801-Q1 regulators enable input and power good output that allow easy sequence with external regulators. These regulators provide precision reference and an error amplifier with 2% accuracy over line, load, temperature, and process. The TPS74801/TPS74801-Q1 LDO is stable with any capacitor greater than or equal to 2.2µF.
The TPS74801 regulators are available in small 3mm × 3mm VSON-10 and 5mm × 5mm VQFN-20 packages. Typical applications include telematic control units, infotainment and cluster, automotive head units, and medium and short-range radars. The TPS74801-Q1 LDO linear regulators are AEC-Q100 qualified for automotive applications.
