12 / 60 page AUTOMOTIVE, 125°C OPERATION, 36 V INPUT, 250 mA VOLTAGE REGULATOR S-19212B/DxxA Series Rev.5.3_00 12 Standard Circuit CIN *1 CL *2 Input Output GND Single GND VOUT VIN VSS ON / OFF *1. CIN is a capacitor for stabilizing the input. *2. CL is a capacitor for stabilizing the output. Figure 14 Caution The above connection diagram and constants will not guarantee successful operation. Perform thorough evaluation using an actual application to set the constants. Condition of Application Input capacitor (CIN): A ceramic capacitor with capacitance of 1.0 μF or more is recommended. Output capacitor (CL): A ceramic capacitor with capacitance of 1.0 μF to 100 μF is recommended. Caution Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external parts. Perform thorough evaluation including the temperature characteristics with an actual application using the above capacitors to confirm no oscillation occurs. Selection of Input Capacitor (CIN) and Output Capacitor (CL) The S-19212B/DxxA Series requires CL between the VOUT pin and the VSS pin for phase compensation. The operation is stabilized by a ceramic capacitor with capacitance of 1.0 μF to 100 μF. When using an OS capacitor, a tantalum capacitor or an aluminum electrolytic capacitor, the capacitance also must be 1.0 μF to 100 μF. However, an oscillation may occur depending on the equivalent series resistance (ESR). Moreover, the S-19212B/DxxA Series requires CIN between the VIN pin and the VSS pin for a stable operation. Generally, an oscillaiton may occur when a voltage regulator is used under the conditon that the impedance of the power supply is high. Note that the output voltage transient characteristics varies depending on the capacitance of CIN and CL and the value of ESR. Caution Perform thorough evaluation including the temperature characteristics with an actual application to select CIN and CL. |
