S-1142A/BxxH Series www.ablic.com www.ablicinc.com HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT 105C OPERATION CMOS VOLTAGE REGULATOR Rev.2.2_02 © ABLIC Inc., 2012-2014 The S-1142A/BxxH Series, developed by using high-withstand voltage CMOS technology, is a positive voltage regulator with a high-withstand voltage, low current consumption, and high-accuracy output voltage. The S-1142A/BxxH Series operates at a high maximum operating voltage of 50 V and a low current consumption of 4.0 A typ. In addition to a built-in low on-resistance transistor which provides a very small dropout voltage and a large output current, this voltage regulator also has a built-in ON / OFF circuit. An overcurrent protection circuit prevents the load current from exceeding the capacitance of the output transistor, and a built-in thermal shutdown circuit prevents damage caused by heat. A high heat radiation HSOP-6 package enables high-density mounting.

Vdrop = VIN1  (VOUT3  0.98) VOUT3 is the output voltage when VIN = VOUT(S)  2.0 V, and IOUT = 100 mA or 200 mA. VIN1 is the input voltage at which the output voltage becomes 98% of VOUT3 after gradually decreasing the input voltage. The output current can be at least this value. Due to limitation of the package power dissipation, this value may not be satisfied. Attention should be paid to the power dissipation of the package when the output current is large.

Figure 10 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): Output capacitor (CL): 0.1 F or more 0.1 F or more Caution Generally a series regulator may cause oscillation, depending on the selection of external parts. Confirm that no oscillation occurs in the application for which the above capacitors are used.  Selection of Input and Output Capacitors (CIN, CL) The S-1142A/BxxH Series requires an output capacitor between the VOUT pin and the VSS pin for phase compensation. Operation is stabilized by a ceramic capacitor with an output capacitance of 0.1 F or more over the entire temperature range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must be 0.1 F or more. The values of output overshoot and undershoot, which are transient response characteristics, vary depending on the value of the output capacitor. The required value of capacitance for the input capacitor differs depending on the application. Set the value for input capacitor (CIN) and output capacitor (CL) as follows. CIN  0.1 F CL0.1 F Caution Define the capacity values of CIN and CL by sufficient evaluation including the temperature characteristics under the actual usage conditions. 11 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT 105C OPERATION CMOS VOLTAGE REGULATOR Rev.2.2_02 S-1142A/BxxH Series  Explanation of Terms 1.

Basic operation Figure 11 shows the block diagram of the S-1142A/BxxH Series. The error amplifier compares the reference voltage (Vref) with feedback voltage (Vfb), which is the output voltage resistance-divided by feedback resistors (Rs and Rf). It supplies the gate voltage necessary to maintain the constant output voltage which is not influenced by the input voltage and temperature change, to the output transistor.

Output transistor In the S-1142A/BxxH Series, a low on-resistance P-channel MOS FET is used as the output transistor. Be sure that VOUT does not exceed VIN0.3 V to prevent the voltage regulator from being damaged due to reverse current flowing from the VOUT pin through a parasitic diode to the VIN pin, when the potential of VOUT became higher than VIN. 13 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT 105C OPERATION CMOS VOLTAGE REGULATOR Rev.2.2_02 S-1142A/BxxH Series 3. ON / OFF pin This pin starts and stops the regulator. When the ON / OFF pin is set to OFF level, the entire internal circuit stops operating, and the built-in P-channel MOS FET output transistor between the VIN pin and the VOUT pin is turned off, reducing current consumption significantly. The VOUT pin is set to the VSS level by the internal dividing resistor of several M between the VOUT pin and the VSS pin. Note that the current consumption increases when a voltage of 0.3 V to VIN  0.3 V is applied to the ON / OFF pin. The ON / OFF pin is configured as shown in Figure 12. Since the ON / OFF pin is neither pulled down nor pulled up internally, do not use it in the floating status. When not using the ON / OFF pin, connect it to the VSS pin in the product A type, and connect it to the VIN pin in the B type.

Overcurrent protection circuit The S-1142A/BxxH Series includes an overcurrent protection circuit having the characteristics shown in "1. Output voltage vs. Output current (When load current increases) (Ta = 25C)" in " Characteristics (Typical Data)", in order to protect the output transistor against an excessive output current and short circuiting between the VOUT pin and the VSS pin. The current when the output pin is short-circuited (Ishort) is internally set at approx. 80 mA typ., and the normal value is restored for the output voltage, if releasing a short circuit once. Caution This overcurrent protection circuit does not work as for thermal protection. If this IC long keeps short circuiting inside, pay attention to the conditions of input voltage and load current so that, under the usage conditions including short circuit, the loss of the IC will not exceed power dissipation of the package. 14 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT 105C OPERATION CMOS VOLTAGE REGULATOR Rev.2.2_02 S-1142A/BxxH Series 5. Thermal shutdown circuit The S-1142A/BxxH Series has a thermal shutdown circuit to protect the device from damage due to overheat. When the junction temperature rises to 150C typ., the thermal shutdown circuit operates to stop regulating. When the junction temperature drops to 125C typ., the thermal shutdown circuit is released to restart regulating. Due to self-heating of the S-1142A/BxxH Series, if the thermal shutdown circuit starts operating, it stops regulating so that the output voltage drops. When regulation stops, the S-1142A/BxxH Series does not itself generate heat and the IC’s temperature drops. When the temperature drops, the thermal shutdown circuit is released to restart regulating, thus this IC generates heat again. Repeating this procedure makes the waveform of the output voltage into a pulse-like form. Stop or restart of regulation 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.

Overshoot of output voltage Overshoot of output voltage occurs depending on the condition such as the rising speed of input voltage (VIN). Overshoot voltage is the difference between the maximum value of output voltage generated by the fluctuation of VIN and the actual output voltage (VOUT(E)) value. 6. 1 At normal operation As shown in Figure 13, Vgs is the voltage difference between VIN and gate voltage of output driver. The error amplifier controls Vgs in order to keep the output voltage constant depending on the fluctuation of VIN and the output load. VIN Vref Vgs  Output driver  Output voltage Output capacitance Output load Figure 13 6. 2 Circuit Diagram Occurrence of overshoot If VIN voltage rises at a fast speed, Vgs may become large when gate voltage of output driver can not follow the speed of VIN. When Vgs becomes large, the current supplied from output driver is increased transiently. Thereby, output voltage rises, and then overshoot occurs. Note that overshoot voltage is greatly affected by the following use conditions or temperature, etc.  When VIN rises in the range of 2.0 V to VOUT(E).  When the rising speed of VIN is fast.  When the output capacitance is small.  When the output load is small. Input voltage (VIN) Rising speed of VIN = V t V VIN = 2.0 V to VOUT(E) Output voltage (VOUT(E)) Overshoot voltage VOUT(E) VIN = 2.0 V to VOUT(E) Rising time (t) Figure 14 Caution VIN and Overshoot Voltage Under the following conditions, overshoot voltage tends to become larger especially.  When VIN rises from around 98% of VOUT(E).  When the rising speed of VIN is 10 mV/s or more. Remark When overshoot of the S-1142A/BxxH Series has some influences, consider to use the S-1142C/DxxH Series. 16 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT 105C OPERATION CMOS VOLTAGE REGULATOR Rev.2.2_02 S-1142A/BxxH Series  Precautions  Wiring patterns for the VIN pin, the VOUT pin and GND should be designed so that the impedance is low. When mounting an output capacitor between the VOUT pin and the VSS pin (CL) and a capacitor for stabilizing the input between the VIN pin and the VSS pin (CIN), the distance from the capacitors to these pins should be as short as possible.  Note that generally the output voltage may increase when a series regulator is used at low load current (0.1 mA or less).  Note that generally the output voltage may increase due to the leakage current from an output driver when a series regulator is used at high temperature.  Note that the output voltage may increase due to the leakage current from an output driver even if the ON / OFF pin is at OFF level when a series regulator is used at high temperature.  Generally a series regulator may cause oscillation, depending on the selection of external parts. The following conditions are recommended for the S-1142A/BxxH Series. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Refer to "6. Example of equivalent series resistance vs. Output current characteristics (Ta =25C)" in " Reference Data" for the equivalent series resistance (RESR) of the output capacitor. Input capacitor (CIN): Output capacitor (CL): 0.1 F or more 0.1 F or more  The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitance is small or an input capacitor is not connected.  Sufficiently evaluate the output voltage fluctuations caused by the power supply or the load fluctuations with the actual device.  Overshoot may occur in the output voltage momentarily if the voltage is rapidly raised at power-on or when the power supply fluctuates. Sufficiently evaluate the output voltage at power-on with the actual device.  The application conditions for the input voltage, the output voltage, and the load current should 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.  In determining the output current, attention should be paid to the output current value specified in Table 8 in " Electrical Characteristics" and footnote *4 of the table.  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. 17 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT 105C OPERATION CMOS VOLTAGE REGULATOR Rev.2.2_02 S-1142A/BxxH Series  Characteristics (Typical Data) 1.
