The XC31P series is a group of temperature sensitive, positive voltage

output, three-pin regulators, that provide voltage in response to sensed

ambient temperatures. This function is very useful for correcting

temperature characteristics of LCD devices etc. It can also be used as a

temperature sensor.

The XC31P consists of a temperature sensor, a voltage correction circuit,

a high-precision voltage reference source, an error correction circuit, and

a current limited output driver.

Laser trimming increases output voltage accuracy and provides output

stability against the variations in input voltage and output current. CMOS

production technology reduces power consumption.

SOT-23 (150mW) and SOT-89 (500mW) packages are available.
