These features help modern appliances meet increasingly stringent energy requirements and help extend battery life in portable-power solutions. The TPS7A24 is available in both fixed and adjustable versions. The fixed-voltage version eliminates external resistors and minimizes printed circuit board (PCB) area. For more flexibility or higher output voltages, the adjustable version uses feedback resistors to set the output voltage from 1.24 V to 17.75 V. Both versions have 2% output regulation accuracy that provides precision regulation for microcontroller (MCU) references. 2 Applications Smoke and heat detectors Thermostats Motion detectors (PIR, uWave, and so forth) Cordless power tools Applia...
