The MAX667EPA+ is a positive-output LDO regulator from Analog Devices, delivering up to 250 mA from a 1.3 V to 16 V adjustable output (a 5 V fixed option is also available). Its 16.5 V maximum input voltage covers typical 12 V and 15 V rails with margin. Dropout voltage is 0.35 V max at 200 mA, meaning the regulator maintains regulation with less than 350 mV headroom between input and output at that load — useful in battery-powered designs where the supply rail sags near end-of-life. Quiescent current is 35 µA typical, and the device includes a dropout detector, enable pin, and low-battery detection — control features that let a system supervisor shut down the regulator or flag a near-dropout condition before the output falls out of regulation.
