Basic operation Figure 13 shows the block diagram of the S-1131 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-1131 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 RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.4.1_02 S-1131 Series 3. ON/OFF pin In case of product with ON/OFF circuit, 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 becomes the Vss level due to the internally divided resistance of several hundreds k between the VOUT pin and the VSS pin. The structure of the ON/OFF pin is as shown in Figure 14. Since the ON/OFF pin is neither pulled down nor pulled up internally, do not use it in the floating states. In addition, note that the current consumption increases if a voltage of 0.3 V to VIN – 0.3 V is applied to the ON/OFF pin. 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 B type. Product Type A A B B ON/OFF Pin “L”: ON “H”: OFF “L”: OFF “H”: ON Table 7 Internal Circuit VOUT Pin Voltage Operate Set value Stop VSS level Stop VSS level Operate Set value Current Consumption ISS1 ISS2 ISS2 ISS1 VIN ON/OFF VSS Figure 14  Selection of Output Capacitor (CL) The S-1131 Series performs phase compensation using the internal phase compensator in the IC and the ESR (Equivalent Series Resistance) of the output capacitor to enable stable operation independent of changes in the output load. Therefore, always place a capacitor (CL) of 2.2 F or more between the VOUT pin and the VSS pin. For stable operation of the S-1131 Series, it is essential to employ a capacitor whose ESR is within an optimum range. Using a capacitor whose ESR is outside the optimum range (approximately 0.5  to 5 ), whether larger or smaller, may cause an unstable output, resulting in oscillation. For this reason, a tantalum electrolytic capacitor is recommended. When a ceramic capacitor or an OS capacitor with a low ESR is used, it is necessary to connect an additional resistor that serves as the ESR in series with the output capacitor. The required resistance value is approximately 0.5  to 5 , which varies depending on the usage conditions, so perform sufficient evaluation for selection. Ordinarily, around 1.0  is recommended. Note that an aluminum electrolytic capacitor may increase the ESR at a low temperature, causing oscillation. When using this kind of capacitor, perform thorough evaluation, including evaluation of temperature characteristics. 14 HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.4.1_02 S-1131 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 (1.0 mA or less).  The S-1131 Series performs phase compensation by using an internal phase compensator and the ESR of an output capacitor. Therefore, always place a capacitor of 2.2 F or more between the VOUT pin and the VSS pin. A tantalum type capacitor is recommended. Moreover, to secure stable operation of the S-1131 Series, it is necessary to employ a capacitor with an ESR within an optimum range (0.5  to 5 ). Using a capacitor whose ESR is outside the optimum range (approximately 0.5  to 5 ), whether larger or smaller, may cause an unstable output, resulting in oscillation. Perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics.  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.  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 6 in “ Electrical Characteristics” and footnote *5 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. 15 HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR
