High-precision Low Voltage Detector

General Description

LP3808 is a series of high precision voltage detector

with ultra low current consumption(500nA typ. at

Vdd=3.0V). It can work at very low voltage, which

makes it perfect for system reset.

LP3808

is

composed

of

high

precision

voltage

reference, comparator, 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.LP3808 is available in SOT-89-3,SOT-23-3, SOT23-5

packages which is Pb free.
