Series Temperature Controlled Voltage Regulators ◆CMOS ◆Output Voltage Range : 1.5V~5.5V ◆Accuracy : ±5% ◆Output Voltage Temperature Coefficient : Typ. -3000ppm/°C ◆Detectable Temperature Range : -20°C~60°C ◆No-Load Supply Current:Typ. 1.0µA ■Applications ■General Description ■Features 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.
