The MAX8718/MAX8719 are micropower, 8-pin TDFN

p owe r to CMOS RAM, re a l-time c loc ks (RTC), a nd  
microcontrollers in systems with high-voltage batteries.  
The circuits consist of a 100mA linear regulator and a  
power-good comparator (PGOOD) with fixed-output  
delay. Key features include wide input voltage range,  
low-dropout voltage, and low-quiescent supply current.

Despite a miserly 25µA (max) no-load quiescent cur-

(MAX8719), even when subjected to fast supply-volt-

Internal foldback current limiting and thermal shutdown  
protect the regulator from overload and thermal faults.
