S-1112/1122 Series www.ablic.com www.ablicinc.com HIGH RIPPLE-REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.6.1_02 (c) ABLIC Inc., 2002-2015 The S-1112/1122 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, and low current consumption developed based on CMOS technology. A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the conventional CMOS technology, a larger variety of capacitors are available, including small ceramic capacitors. Small SNT-6A(H) (S-1112 Series only) and SOT-23-5 packages realize high-density mounting. In SOT-23-5, the lineup includes the S-1112 and S-1122 Series, which differ in pin configuration.

Low dropout voltage regulator This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor. 2. Low ESR A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1112/1122 Series enables use of a low ESR capacitor, such as a ceramic capacitor, for the output-side capacitor (CL). A capacitor whose ESR is 10 or less can be used. 3. Output voltage (VOUT) The accuracy of the output voltage is ensured at 1.0% under the specified conditions of fixed input voltage*1, fixed output current, and fixed temperature. *1. Differs depending 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. VOUT1 V INVOUT 4. Line regulation Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output voltage changes due to a change in the input voltage with the output current remaining unchanged. 5. Load regulation (VOUT2) Indicates the dependency of the output voltage on the output current. That is, the values show how much the output voltage changes due to a change in the output current with the input voltage remaining unchanged. 6. Dropout voltage (Vdrop) Indicates the difference between input voltage (VIN1) and the output voltage when; decreasing input voltage (VIN) gradually until the output voltage has dropped out to the value of 98% of output voltage (VOUT3), which is at VIN = VOUT(S) 1.0 V.

Basic operation Figure 12 shows the block diagram of the S-1112/1122 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 Current supply Error amplifier Vref VOUT Rf Vfb Reference voltage circuit Rs VSS *1. Parasitic diode Figure 12 2. Output transistor In the S-1112/1122 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. 14 HIGH RIPPLE-REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.6.1_02 S-1112/1122 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 becomes the VSS level due to the internally divided resistance of several M between the VOUT pin and the VSS pin. The structure of the ON/OFF pin is as shown in Figure 13. Since the ON/OFF pin is neither pulled down nor pulled up internally, do not use it in the floating status. 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.

A ceramic capacitor with a capacitance of 0.47 F or more can be used. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must be 0.47 F or more, and the ESR must be 10 or less. The value of the output overshoot or undershoot transient response varies depending on the value of the output capacitor. When selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device. 15 HIGH RIPPLE-REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.6.1_02 S-1112/1122 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). Generally a series regulator may cause oscillation, depending on the selection of external parts. The following conditions are recommended for the S-1112/1122 Series. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Input capacitor (CIN): 1.0 F or more Output capacitor (CL): 0.47 F or more Equivalent series resistance (ESR): 10 or less 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 7 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. 16 HIGH RIPPLE-REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.6.1_02 S-1112/1122 Series Characteristics (Typical Data) Remark The following, which describes the S-1112 Series as the typical product, shows typical data common to the S-1122 Series.
