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.
