The MAX8718/MAX8719 are micropower, 8-pin TDFNlinear regulators that supply always-on, keep-alivepower to CMOS RAM, real-time clocks (RTC), andmicrocontrollers in systems with high-voltage batteries.The circuits consist of a 100mA linear regulator and apower-good comparator (PGOOD) with fixed-outputdelay. Key features include wide input voltage range,low-dropout voltage, and low-quiescent supply current.Despite a miserly 25µA (max) no-load quiescent current,the MAX8718/MAX8719 have good line- and loadtransientresponse and excellent AC power-supplyrejection. They provide a clean fixed 5V or 3.3V output(MAX8718), or an adjustable 1.24V to 28V output(MAX8719), even when subjected to fast supply-voltagechanges that occur during the switchover from batteryto AC-adapter input power. The space-savingTDFN package has excellent thermal characteristicsand tolerates up to 1951mW of power dissipation.Internal foldback current limiting and thermal shutdownprotect the regulator from overload and thermal faults.In addition to the main notebook-computer application,these devices are useful in other low-power, high-voltageapplications (4V IN The MAX8718/MAX8719 are available in a thermallyenhanced 3mm x 3mm, 8-lead TDFN package.ApplicationsBattery-Powered SystemsCMOS/RTC Backup PowerMicrocontroller PowerNotebook ComputersPDAs and Handy-TerminalsSmart Battery Packs/Chargers
