As a bandgap type temperat ure 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 -30ˆ to +80 ˆ. The XC31B comes in a mini molded SOT-25 and USP-6B packages with a supply current of only 7ЖA (@VOUT=2.0V) and as such, is suitable for use with various portable devices. Output voltage is selectable in 100mV increments within a range of 2.0V to 6.0V (at 25ˆ). ˙APPLICATIONS ˔Mobile phones ˔Portable AV equipment ˔Palm top computers, PDAS ˔Battery powered equipment ˙PIN CONFIGURATION ˙FEATURES Operating Voltage Range : 3.0V ~ 10.0V Output Voltage Range : 2.0V~ 6.0V Output Voltage Accuracy : ʶ3% Detectable Temperature Range : -30 ˆ ~ +80 ˆ Output Voltage Temp. Coefficient : -3900ppm/ˆ (TYP.) Low Power Consumption : 7ЖA (@VOUT=2.0V) Packages : SOT-25, USP-6B ˙PIN ASSIGNMENT *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 SS pin. VSS NC CE VIN NC VOUT ETR0901_001

If this IC is to be used in applications where such currents are required, please use a buffer on the output *3: Output voltage temperature coefficient (TD) is defined as: XC31BPN40A VOUT(T) (*1) =4.0V *4: Linearity margin error (TL) is calculated as follows: where emax = maximum error. The maximum error is the maximum difference between the actual measured value and the value on an approximated straight line. T D = △V OUT Ta ・V OUT T L = emax Tse ・△ Ta
˙NOTE ON USE 1. When the load capacitance CL is too large, oscillation may occur on the output signal. 2. Output signal overshoot will occur when the power (VIN) is switched on or when the power drastically fluctuates. The chip enable (CE) function is effective for helping to avoid overshoot and also in saving consumption current. ˙TYPICAL APPLICATION CIRCUIT
