The MAX16999 linear regulator operates from a 2.5V to 5.5V input voltage and delivers 100mA continuous load current with a low quiescent current typically around 13µA. The output voltage is preset to internally trimmed voltages in the 0.5V to 3.3V range (see the Selector Guide in the full data sheet). An active-low, open-drain reset output remains low for a programmable timeout delay after the output voltage reaches regulation. The reset timeout is programmed by an external capacitor connected to CRES.
This device also features logic-controlled shutdown, and short-circuit and thermal-overload protection. The typical applications are multimedia, telematics, and motor control microcontrollers (µCs) with always-on requirements. The MAX16999 is used as a parallel, low-quiescent supply to power the core or interrupt section of µCs during sleep mode. It can also be used to supply a timer or memory during µC shutoff. The adjustable POR delay assists with power-supply sequencing.
