A ceramic capacitor with capacitance of 2.2 μF or more 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-19244xxxA 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 2.2 μF or more. When using an OS capacitor, a tantalum capacitor or an aluminum electrolytic capacitor, the capacitance also must be 2.2 μF or more. However, an oscillation may occur depending on the equivalent series resistance (ESR). Moreover, the S-19244xxxA 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. Selection of Capacitor for Soft-start (CSS) The S-19244xxxA Series E / F / G / H type requires the capacitor for soft-start (CSS) between the SSC pin and the VSS pin. Over the entire temperature range, the S-19244xxxA Series operates stably with a ceramic capacitor of 0.68 nF or more. According to CSS capacitance, the rising speed of the output voltage is adjustable. The time that the output voltage rises to 99% is 6.0 ms typ. at CSS = 10 nF. The recommended value for applications is 0.68 nF ≤ CSS ≤ 168 nF, however; define the values by sufficient evaluation including the temperature characteristics under the usage condition. Selection of Resistor for Output Voltage External Setting (Ra, Rb) The S-19244xxxA Series provides the types in which output voltage can be set via the external resistor. The output voltage can be set by connecting a resistor (Ra) between the VOUT pin and the VADJ pin, and a resistor (Rb) between the VADJ pin and the VSS pin. Depending on the intended output voltage, select Ra and Rb from the range shown in Table 22. Caution Since the VADJ pin impedance is comparatively high and is easily affected by noise, pay adequate attention to the wiring pattern.

Differs depending on the product. Caution 3. If the certain condition is not satisfied, the output voltage may exceed the accuracy range of ±2.3%. Refer to " Electrical Characteristics" and " Characteristics (Typical Data)" for details. ΔVOUT1 ΔVIN • VOUT Line regulation Indicates the dependency of the output voltage against the input voltage. That is, the value shows how much the output voltage changes due to a change in the input voltage after fixing output current constant. 4. Load regulation (ΔVOUT2) Indicates the dependency of the output voltage against the output current. That is, the value shows how much the output voltage changes due to a change in the output current after fixing input voltage constant. 5. Dropout voltage (Vdrop) Indicates the difference between input voltage (VIN1) and the output voltage when the output voltage becomes 98% of the output voltage value (VOUT3) at VIN = VOUT(S) + 1.0 V after the input voltage (VIN) is decreased gradually.

Basic operation Figure 27 shows the block diagram of the S-19244xxxA Series to describe the basic operation. The error amplifier compares the feedback voltage (Vfb) whose output voltage (VOUT) is divided by the feedback resistors (Rs and Rf) with the reference voltage (Vref). The error amplifier controls the output transistor, consequently, the regulator starts the operation that holds VOUT constant without the influence of the input voltage (VIN). VIN *1 Current supply VOUT Error amplifier Vref − + Rf Vfb Reference voltage circuit Rs VSS *1. Parasitic diode Figure 27 2. Output transistor In the S-19244xxxA Series, a low on-resistance P-channel MOS FET is used between the VIN pin and the VOUT pin as the output transistor. In order to hold VOUT constant, the on-resistance of the output transistor varies appropriately according to the output current (IOUT). Caution Since a parasitic diode exists between the VIN pin and the VOUT pin due to the structure of the transistor, the IC may be damaged by a reverse current if VOUT becomes higher than VIN. Therefore, be sure that VOUT does not exceed VIN + 0.3 V. 25 FOR AUTOMOTIVE 125°C OPERATION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR WITH SOFT-START FUNCTION Rev.2.0_00 S-19244xxxA Series 3. ON / OFF pin The ON / OFF pin controls the internal circuit and the output transistor in order to start and stop the regulator. When the ON / OFF pin is set to OFF, the internal circuit stops operating and the output transistor between the VIN pin and the VOUT pin is turned off, reducing current consumption significantly. Note that the current consumption increases when a voltage of 0.6 V to VIN − 0.3 V is applied to the ON / OFF pin. The ON / OFF pin is configured as shown in Figure 28 and Figure 29. 3. 1 S-19244xxxA Series A / C / E / G type Since the ON / OFF pin is internally pulled down to the VSS pin in the floating status, the VOUT pin is set to the VSS level. Refer to " Electrical Characteristics" for the ON / OFF pin current. 3. 2 S-19244xxxA Series B / D / F / H type Since the ON / OFF pin is neither pulled down nor pulled up, do not use these types in the floating status. When not using the ON / OFF pin, connect it to the VIN pin.

Note that the IC's current consumption increases as much as current flows into the pull-down resistor when the ON / OFF pin is connected to the VIN pin and the S-19244xxxA Series A / C / E / G type is operating (refer to Figure 28). *3. The VOUT pin voltage is pulled down to VSS due to the discharge shunt circuit (RLOW = 100 Ω typ.), the feedback resistors (Rs and Rf) and a load.

Discharge shunt function (S-19244xxxA Series A / B / E / F type) The S-19244xxxA Series A / B / E / F type has a built-in discharge shunt circuit to discharge the output capacitance. The output capacitance is discharged as follows so that the VOUT pin reaches the VSS level. (1) The ON / OFF pin is set to OFF level. (2) The output transistor is turned off. (3) The discharge shunt circuit is turned on. (4) The output capacitor discharges. Since the S-19244xxxA Series C / D / G / H type does not have a discharge shunt circuit, the VOUT pin is set to the VSS level through several hundred kΩ internal divided resistors between the VOUT pin and the VSS pin. The S-19244xxxA Series A / B / E / F type allows the VOUT pin to reach the VSS level rapidly due to the discharge shunt circuit.

Parasitic diode Figure 30 5. Pull-down resistor (S-19244xxxA Series A / C / E / G type) The ON / OFF pin is internally pulled down to the VSS pin in the floating status, so the VOUT pin is set to the VSS level. Note that the IC's current consumption increases as much as current flows into the pull-down resistor of 4.0 MΩ typ. when the ON / OFF pin is connected to the VIN pin. 27 FOR AUTOMOTIVE 125°C OPERATION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR WITH SOFT-START FUNCTION Rev.2.0_00 S-19244xxxA Series 6. Overcurrent protection circuit The S-19244xxxA Series has a built-in overcurrent protection circuit to limit the overcurrent of the output transistor. When the VOUT pin is shorted with the VSS pin, that is, at the time of the output short-circuit, the output current is limited to 330 mA typ. due to the overcurrent protection circuit operation. The S-19244xxxA Series restarts regulating when the output transistor is released from the overcurrent status. Caution 7. This overcurrent protection circuit does not work as for thermal protection. For example, when the output transistor keeps the overcurrent status long at the time of output short-circuit or due to other reasons, pay attention to the conditions of the input voltage and the load current so as not to exceed the power dissipation. Thermal shutdown circuit The S-19244xxxA Series has a built-in thermal shutdown circuit to limit overheating. When the junction temperature increases to 170°C typ., the thermal shutdown circuit becomes the detection status, and the regulating is stopped. When the junction temperature decreases to 135°C typ., the thermal shutdown circuit becomes the release status, and the regulator is restarted. If the thermal shutdown circuit becomes the detection status due to self-heating, the regulating is stopped and VOUT decreases. For this reason, the self-heating is limited and the temperature of the IC decreases. The thermal shutdown circuit becomes release status when the temperature of the IC decreases, and the regulating is restarted after the soft-start operation is finished, thus the self-heating is generated again. Repeating this procedure makes the waveform of VOUT into a pulse-like form. This phenomenon continues unless decreasing either or both of the input voltage and the output current in order to reduce the internal power consumption, or decreasing the ambient temperature. Note that the product may suffer physical damage such as deterioration if the above phenomenon occurs continuously. Caution When the heat radiation of the application is not in a good condition, the self-heating cannot be limited immediately, and the IC may suffer physical damage. Perform thorough evaluation with an actual application to confirm no problems happen.

Types in which output voltage is externally set The S-19244xxxA Series provides the types in which output voltage can be set via the external resistor. The output voltage can be set by connecting a resistor (Ra) between the VOUT pin and the VADJ pin, and a resistor (Rb) between the VADJ pin and the VSS pin. The output voltage is determined by the following formulas. VOUT = 1.0 + Ra × la ···················· (1) By substituting Ia = IVADJ + 1.0 / Rb to above formula (1), VOUT = 1.0 + Ra × (IVADJ + 1.0 / Rb) = 1.0 × (1.0 + Ra / Rb) + Ra × IVADJ ······· (2) In above formula (2), Ra × IVADJ is a factor for the output voltage error. Whether the output voltage error is minute is judged depending on the following (3) formula. By substituting IVADJ = 1.0 / RVADJ to Ra × IVADJ VOUT = 1.0 × (1.0 + Ra / Rb) + 1.0 × Ra / RVADJ ················ (3) If RVADJ is sufficiently larger than Ra, the error is judged as minute. VOUT Ia VIN IVADJ VADJ RVADJ Ra VOUT 1.0 V Ib Rb VSS Figure 32 The following expression is in order to determine VOUT = 6.0 V. If Rb = 2 kΩ, substitute RVADJ = 600 kΩ typ. into (3), Ra = (6.0 / 1.0 − 1) × ((2 k × 600 k) / (2 k + 600 k)) ≅ 9.97 kΩ Caution The above connection diagrams and constants will not guarantee successful operation.

Perform thorough evaluation including the temperature characteristics with an actual application to select CIN. • Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external parts. The following use conditions are recommended in the S-19244xxxA Series; however, perform thorough evaluation including the temperature characteristics with an actual application to select CIN and CL. Input capacitor (CIN): A ceramic capacitor with capacitance of 2.2 μF or more is recommended. Output capacitor (CL): A ceramic capacitor with capacitance of 2.2 μF or more is recommended. • Generally, in a voltage regulator, the values of an overshoot and an undershoot depending on the variation factors of input voltage start-up, input voltage fluctuation, capacitance of CIN or CL and the value of the equivalent series resistance (ESR), which stable operation. Perform thorough evaluation including the temperature characteristics select CIN and CL. in the output voltage vary load fluctuation etc., or the may cause a problem to the with an actual application to • Generally, in a voltage regulator, an overshoot may occur in the output voltage momentarily if the input voltage steeply changes when the input voltage is started up, the soft-start operation is performed, the input voltage fluctuates, etc. Perform thorough evaluation including the temperature characteristics with an actual application to confirm no problems happen. • Generally, in a voltage regulator, if the VOUT pin is steeply shorted with GND, a negative voltage exceeding the absolute maximum ratings may occur in the VOUT pin due to resonance phenomenon of the inductance and the capacitance including CL on the application. The resonance phenomenon is expected to be weakened by inserting a series resistor into the resonance path, and the negative voltage is expected to be limited by inserting a protection diode between the VOUT pin and the VSS pin. • If the input voltage is started up steeply under the condition that the capacitance of CL is large, the thermal shutdown circuit may be in the detection status by self-heating due to the charge current to CL. • Make sure of the conditions for the input voltage, output voltage and the load current so that the internal loss does not exceed the power dissipation. • Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. • When considering the output current value that the IC is able to output, make sure of the output current value specified in Table 20 and Table 21 in " Electrical Characteristics" and footnote *5 of the table. • Wiring patterns on the application related to the VIN pin, the VOUT pin and the VSS pin should be designed so that the impedance is low. When mounting CIN between the VIN pin and the VSS pin and CL between the VOUT pin and the VSS pin, connect the capacitors as close as possible to the respective destination pins of the IC. • When setting the output voltage by using an external resistor, connect a resistor (Ra) between the VOUT pin and the VADJ pin and a resistor (Rb) between the VADJ pin and the VSS pin close to the respective pins. • In the package equipped with heat sink of backside, mount the heat sink firmly. Since the heat radiation differs according to the condition of the application, perform thorough evaluation with an actual application to confirm no problems happen. • SII Semiconductor Corporation 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. 32 FOR AUTOMOTIVE 125°C OPERATION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR WITH SOFT-START FUNCTION Rev.2.0_00 S-19244xxxA Series Characteristics (Typical Data) Output voltage vs. Output current (When load current increases) (Ta = +25°C) VOUT = 1.0 V VOUT [V] 1. 1 1. 2 3.6 1.0 3.0 0.8 VIN = 2.5 V 0.6 VIN = 3.0 V 0.4 VIN = 3.5 V VIN = 4.0 V VIN = 5.0 V 2.4 1.8 1.2 0.6 0.2 0.0 0.0 0 1. 3 VOUT = 3.0 V 1.2 VOUT [V] 1. 250 500 750 1000 1250 1500 1750 2000 IOUT [mA] 0 250 500 750 1000 1250 1500 1750 2000 IOUT [mA] VOUT = 6.0 V 7.2 VOUT [V] 6.0 VIN = 6.5 V VIN = 7.0 V VIN = 8.0 V 4.8 3.6 2.4 1.2 0.0 0 Remark 250 500 750 1000 1250 1500 1750 2000 IOUT [mA] In determining the output current, attention should be paid to the following. 1.
