Ultra-Low Output Voltage, Low-Quiescent-Current Linear Regulator For High-Temperature Applications

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 13A. The output voltage is preset to internally trimmed voltages in the 0.5V to 3.3V range (see the Selector Guide). An active-low, open-drain reset output remains low for a programmable timeout delay after the output voltage reaches regulation. The reset timeout is pro- grammed 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 (Cs) with always-on requirements. The MAX16999 is used as a parallel, low- quiescent supply to power the core or interrupt section of Cs during sleep mode. It CAN also be used to sup- ply a Timer or memory during C shutoff. The adjustable POR delay assists with power-supply sequencing. By Maxim Integrated Products
