XC31B Series
ETR0901_002
CMOS Temperature Sensor
■GENERAL DESCRIPTIO N
The XC31B series are ultra small CMOS temperature sensor ICs. As a ban dgap 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
(@V
OUT=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℃).

*The dissipation pad for the USP-6B
package should be solder-plated in
recommended mount pattern and metal
masking so as to enhance mounting
strength and heat release.
If the pad needs to be connected to other
pins, it should be connected to the V
