LP3811C 0.9-6 0.9-6 Low 240 High precision,ultra low current consumption SOT23


Reset, Low Voltage Detector Built-in Delay 200ms



General Description

LP3818 is a series of high precision voltage detector with ultra low current consumption (5uA typ. at Vdd=3.0V). It can work at very low voltage, which makes it perfect for system reset. LP3818 is composed of high precision voltage reference, comparator, delay circuit, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming. Two type of output, CMOS and N-channel open-drain are available.LP3818 is available in SOT-23-3 packages which is Pb free.
