It is recommended not to use an external capacitor between the VOUT and VSS pin. When using an external capacitor, set near the VOUT pin. When connecting an A/D converter etc. to the VOUT pin, the input pin capacitance of the A/D converter and the parasitic capacitance component between wires are included as load capacitance. To prevent oscillation, it is recommended to use the following output load condition. Load capacitance of VOUT pin (CL1) : 300 pF or less VDD S-58LM20A VOUT Series VSS CL1 CIN VOUT Figure 11 Caution The above connection diagram and constant will not guarantee successful operation. Perform through evaluation using the actual application to set the constant. 12 CMOS TEMPERATURE SENSOR IC S-58LM20A Series Rev.3.1_02 In this IC, it is necessary to add a capacitor from an output pin to GND with a series resistor in the ambience having excessive noise, as seen in Figure 12 and Figure 13. In the combination shown in Table 7, a time constant against heat of this IC is much later than the time constant composed of RC, therefore it does not affect on the response time of this IC.

Perform thorough evaluation using the actual application to set the constant. 13 CMOS TEMPERATURE SENSOR IC S-58LM20A Series Rev.3.1_02  For stabilization, set a capacitor (CIN) of approx. 0.1 F between VDD and VSS pin.  Do not connect a pull-up resistor to the output pin.  The application condition for input voltage, output voltage and load voltage must not exceed the package power dissipation.  Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit.  Regarding the current at the output pin, refer to load regulation and footnote *1 in Table 6 “ Electrical Characteristics”.  ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party. 14 CMOS TEMPERATURE SENSOR IC S-58LM20A Series Rev.3.1_02  Characteristics (Typical Data) 1.
