Figure 10 Caution The above connection diagram and constant will not guarantee successful operation. Perform through evaluation using the actual application to set the constant. Technical Terms 1. Low dropout voltage regulator The low dropout voltage regulator is a voltage regulator having a low dropout voltage characteristic due to the internal low on-resistance transistor. 2. Output voltage (VOUT) The accuracy of the output voltage is ensured at ±2.0 % under the specified conditions of input voltage, output current, and temperature, which differ product by product. Caution When the above conditions are changed, the output voltage may vary and go out of the accuracy range of the output voltage. Refer to the “ Electrical Characteristics” and “ Characteristics” for details. 3. Line regulation 1 (∆VOUT1) and Line regulation 2 (∆VOUT2) Line regulation indicates the input voltage dependence of the output voltage. The value shows how much the output voltage changes due to the change of the input voltage when the output current is kept constant. 10 Seiko Instruments Inc. Rev.2.1_00 4.

Dropout voltage (Vdrop) Let VIN1 be an input voltage where the output voltage falls to the 98 % of the actual output voltage (VOUT(E)) when gradually decreasing input voltage.

Basic Operation Rev.2.1_00 Figure 12 shows the block diagram of the S-818 Series. The error amplifier compares a reference voltage (Vref) with the part of the output voltage divided by the feedback resistors Rs and Rf. It supplies the output transistor with the gate voltage, necessary to ensure certain output voltage free of any fluctuations of input voltage and temperature. VIN *1 Current source Error amplifier Vref − + Rf VOUT Reference voltage circuit RS VSS *1. Parasitic diode Figure 12 Block diagram 2. Output Transistor The S-818 Series uses a Pch MOS FET 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 flowing from VOUT pin through a parasitic diode to VIN pin. 12 Seiko Instruments Inc. Rev.2.1_00 3. ON/OFF pin (Shutdown pin) LOW DROPOUT CMOS VOLTAGE REGULATOR S-818 Series This pin activates and inactivates the regulator. When the ON/OFF pin is switched to the shutdown level, the operation of all internal circuit stops, the built-in Pch MOS FET output transistor between VIN and VOUT pin is switched off, suppressing current consumption. The VOUT pin goes to the Vss level due to internal divided resistance of several MΩ between VOUT pin and VSS pin. The structure of the ON/OFF pin is shown in Figure 13. Since the ON/OFF pin is neither pulled down nor pulled up internally, do not keep it in the floating state. Current consumption increases if a voltage of 0.3 V to VIN−0.3 V is applied to the ON/OFF pin. When the shutdown pin is not used, connect it to the VIN pin for product type "A" and to the VSS pin for product type "B".

A small ceramic or an OS electrolyte capacitor of 2 µF or more can be used. When a tantalum or an aluminum electrolyte capacitor is used, the capacitance must be 2 µF or more and the ESR must be 10 Ω or less. Attention should be paid not to cause an oscillation due to increase of ESR at low temperatures when an aluminum electrolyte capacitor is used. Evaluate the performance including temperature characteristics before prototyping the circuit. Overshoot and undershoot characteristics differ depending upon the type of the output capacitor. Refer to the “CL dependence” data in “ Transient Response Characteristics”. Seiko Instruments Inc. 13 LOW DROPOUT CMOS VOLTAGE REGULATOR S-818 Series Precautions Rev.2.1_00 • Wiring patterns for the VIN pin, VOUT pin and GND pin should be designed so that the impedance is low. When mounting an output capacitor (CL) or an input capacitor (CIN), the distance from the capacitor to the VOUT pin and to the VSS pin should be as short as possible. • Note that output voltage may increase when a voltage regulator is used at low load current (Less than 10 µA). • To prevent oscillation, the external components should be used under the following conditions: Input capacitor (CIN): 0.47µF or more Output capacitor (CL): 2 µF or more Equivalent series resistance (ESR): 10 Ω or less 10 Ω or less Input series resistance (RIN): • The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small or not connected. • The application condition for input voltage and load current should not exceed the package power dissipation. • In determining output current, attention should be paid to the output current value specified and footnote *5 in Table 5 in the “ Electrical Characteristics”. • Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. • SII claims no responsibility for any and all disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party. 14 Seiko Instruments Inc. Rev.2.1_00 Characteristics (Typical data) LOW DROPOUT CMOS VOLTAGE REGULATOR S-818 Series 1.
