S-1142 Series www.sii-ic.com HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.3.0_00 (c) Seiko Instruments Inc., 2009-2012 The S-1142 Series, developed based on high-withstand voltage CMOS process, is a positive voltage regulator with a high-withstand voltage, low current consumption, and high output voltage accuracy. The S-1142 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 protector 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 x 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.

CIN is a capacitor for stabilizing the input. *2. Ceramic capacitor of 0.1 F or more can be used as CL. 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. Application Conditions Input capacitor (CIN): Output capacitor (CL): 0.1 F or more 0.1 F or more (ceramic capacitor) Caution Generally, series regulator may oscillate depending on the external components. Confirm that no oscillation occur in the application for which the above capacitors are used. Selection of Input and Output Capacitors (CIN, CL) The S-1142 Series requires an output capacitor between the VOUT and VSS pins 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. Seiko Instruments Inc. 11 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR S-1142 Series Rev.3.0_00 Explanation of Terms 1. Low dropout voltage regulator This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor. 2. Output voltage (VOUT) The accuracy of the output voltage is ensured at 3.0% under specified conditions of fixed input voltage*1, fixed output current, and fixed temperature. *1. Differs depending on the product. Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range of the output voltage. Refer to " Electrical Characteristics" and " Characteristics (Typical Data)" for details. 3. VOUT1 Line regulation V * V IN OUT 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 (VOUT2) 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 the output voltage and the input voltage VIN1, which is the input voltage (VIN) when decreasing input voltage VIN gradually until the output voltage has dropped to the value of 98% of output voltage VOUT3, which is at VIN = VOUT(S) + 2.0 V. Vdrop = VIN1 - (VOUT3 x 0.98) 12 Seiko Instruments Inc. Rev.3.0_00 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR S-1142 Series Operation 1. Basic operation Figure 11 shows a block diagram of the S-1142 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. VIN *1 Constant current supply Error amplifier Vref VOUT - + Rf Vfb Reference voltage circuit Rs VSS *1. Parasitic diode Figure 11 2. Output transistor In the S-1142 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 inverse current which flows, because of a parasitic diode between the VIN and VOUT pins, when the potential of VOUT becomes higher than VIN. Seiko Instruments Inc. 13 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR S-1142 Series 3. Rev.3.0_00 ON / OFF pin This pin starts and stops the regulator. When the ON / OFF pin is set to the power-off level, the entire internal circuit stops operating, and the built-in P-channel MOS FET output transistor between the VIN and VOUT pins is turned off, in order to reduce the current consumption significantly. The VOUT pin is set to the VSS level by the internal dividing resistor of several M between the VOUT and VSS pins. 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 state. 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 protector The S-1142 Series includes an overcurrent protection circuit which has the characteristics shown in "1. Output voltage vs. Output current (when load current is increased) (Ta = +25C)" in " Characteristics (Typical Data)", in order to protect the output transistor against an excessive output current and short circuiting between the VOUT and VSS pin. The current (ISHORT) when the output pin is short-circuited is internally set at approx. 80 mA typ., and the initial value is restored for the output voltage, if releasing a short circuit once. Caution Using the overcurrent protection circuit is to protect the output transistor from accidental conditions such as short circuited load and the rapid and large current flow in the large capacitor. The overcurrent protection circuit is not suitable for use under the short circuit status or large current flowing (200 mA or more) that last long. 14 Seiko Instruments Inc. Rev.3.0_00 5. HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR S-1142 Series Thermal shutdown circuit The S-1142 Series has a thermal shutdown circuit to protect the device from damage due to overheat. When the junction temperature rises to 150C typ., the thermal shutdown circuit operates to stop regulating. When the junction temperature drops to 125C typ., the thermal shutdown circuit is released to restart regulating. Due to self-heating of the S-1142 Series, if the thermal shutdown circuit starts operating, it stops regulating so that the output voltage drops. When regulation stops, the S-1142 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 both of the input voltage and the output voltage in order to reduce the internal current consumption, or decreasing the ambient temperature.

VOUT Pin Voltage VSS level Set value Junction temperature Seiko Instruments Inc. 15 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR S-1142 Series Rev.3.0_00 Precautions * Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low. When mounting an output capacitor between the VOUT and VSS pins (CL) and a capacitor for stabilizing the input between the VIN and VSS pins (CIN), the distance from the capacitors to these pins should be as short as possible. * Note that the output voltage may generally increase when a series regulator is used at low load current (0.1 mA or less). * Note that the output voltage may generally increase due to the leakage current from a driver when a series regulator is used at a high temperature. * Note that the output voltage may increase due to the leakage current from a driver even if the ON / OFF pin is at the power-off level when a series regulator is used at a high temperature. * Generally series regulators may oscillate, depending on the selection of external parts. The following conditions are recommended for the S-1142 Series. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including the temperature characteristics. Regarding the equivalent series resistance (RESR) for the output capacitor, refer to "6. Example of equivalent series resistance vs. Output current characteristics (Ta = +25C)" in " Reference Data". 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 of the IC is small, or an input capacitor is not connected. * It is important to sufficiently evaluate in an actual device output voltage fluctuations caused by power supply or load fluctuations. * A momentary overshoot may be output when the power supply suddenly increases, and the output capacitance is small. It is therefore important to sufficiently evaluate the output voltage at power application in actual device. * The application conditions for the input voltage, output voltage, and load current should not exceed power dissipation of the package. * 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 7 in " Electrical Characteristics" and footnote *4 of the table. * SII 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. 16 Seiko Instruments Inc.
