XC31B series is Discontinued. XC31B Series ETR0901_002a CMOS Temperature Sensor ■GENERAL DESCRIPTION The XC31B series are ultra small CMOS temperature sensor ICs. As a bandgap type temperature sensor is built-into the XC31B, linearity, in comparison to thermistor type temperature sensors, is much better. The operating temperature range of the series is from -30℃ to +80℃. The XC31B comes in a mini molded SOT-25 and USP-6B packages with a supply current of only 7μA (@VOUT=2.0V) and as such, is suitable for use with various portable devices. Output voltage is selectable in 0.1V increments within a range of 2.0V to 6.0V (at 25℃). ■FEATURES ■APPLICATIONS Operating Voltage Range : 3.0V ~ 10.0V ●Mobile phones Output Voltage Range : 2.0V~ 6.0V ●Po
