Rev.1.1_00 HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR S-1172 Series The S-1172 Series, developed based on CMOS technology, is a positive voltage regulator with a super low dropout voltage, high output voltage accuracy, and low current consumption. The S-1172 Series provides the very small dropout voltage and the large output current due to the built-in transistor with low on-resistance. The overcurrent protector prevents the load current from exceeding the capacitance of output transistor. The thermal shutdown circuit prevents damage caused by heat, the rush current control circuit limits the excessive rush current during start-up. The ON/OFF circuit ensures longer battery life. Various capacitors, also small ceramic capacitors, can be used for this IC more than for the conventional regulator ICs which have CMOS technology. The packages, high heat radiation HSOP-6 and small SOT-89-5 enable high-density mounting.

CL *2 GND CIN is a capacitor for stabilizing the input. Ceramic capacitor of 4.7 µF or more can be used as CL. Figure 11 Caution The above connection diagram and constant will not guarantee successful operation. Perform thorough evaluation using the actual application to set the constant. Application Conditions Input capacitor (CIN) : 4.7 µF or more Output capacitor (CL) : 4.7 µF or more (ceramic capacitor) Caution 1. Set input capacitor (CIN) and output capacitor (CL) as CIN = CL. 2. Generally, series regulator may oscillate depending on the external components. 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-1172 Series requires an output capacitor between the VOUT and VSS pin for phase compensation. Operation is stabilized by a ceramic capacitor with an output capacitance of 4.7 µF or more over the entire temperature range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must be 4.7 µF or more. The values of output overshoot and undershoot, which are transient response characteristics, vary depending on the value of 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 ≥ 4.7 µF CL ≥ 4.7 µF CIN = CL Caution The S-1172 Series may oscillate if setting the value as CIN ≥ 4.7 µF, CL ≥ 4.7 µF, CIN < CL. Define the values by sufficient evaluation including the temperature characteristics under the usage condition. Seiko Instruments Inc. 11 HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR S-1172 Series Rev.1.1_00 Explanation of Terms 1. Low dropout voltage regulator This IC’s voltage regulator has the low dropout voltage due to its built-in transistor with low on-resistance. 2. Output voltage (VOUT) The accuracy of the output voltage is ensured at ±1.0% or ±15 mV*2 under the specified conditions of fixed input voltage*1, fixed output current, and fixed temperature. *1. *2. Differs depending on the product. When VOUT < 1.5 V : ±15 mV, When 1.5 V ≤ VOUT : ±1.0% Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range of the output voltage. See “ Electrical Characteristics” and “ Characteristics (Typical Data)” for details. 3. Line regulation ∆VOUT1 ∆VIN • VOUT 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 output current 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) + 1.0 V or 5.5 V.

Basic operation Figure 13 shows the block diagram of the S-1172 Series. The error amplifier compares the reference voltage (Vref) with 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-1172 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 pin, when the potential of VOUT became higher than VIN. 14 Seiko Instruments Inc. HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR S-1172 Series Rev.1.1_00 3. Shutdown pin (ON/OFF pin) This pin starts and stops the regulator. When the ON/OFF pin is set to the shutdown level, the entire internal circuit stops operating, and the built-in P-channel MOS FET output transistor between the VIN and VOUT pin 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 hundred kΩ between the VOUT and VSS pin. Note that the current consumption increases when a voltage of 0.3 V to 1.0 V is applied to the ON/OFF pin. The ON/OFF pin is configured 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 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 B type.

Overcurrent protection circuit The S-1172 Series has an overcurrent protection circuit having the characteristics shown in (1) Output Voltage vs. Output Current (When load current is increased) (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 and VSS pin. The current (ISHORT) when the output pin is short-circuited is internally set at approx. 200 mA (Typ.), and the initial 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. Seiko Instruments Inc. 15 HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR S-1172 Series 5. Rev.1.1_00 Thermal shutdown circuit The S-1172 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 120°C (Typ.), the thermal shutdown circuit is released to restart regulating. Due to self-heating of the S-1172 Series, if the thermal shutdown circuit starts operating, it stops regulating so that the output voltage drops. When regulation stops, the S-1172 does not itself generate heat so that 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 waveform of the output voltage pulse-like form. Stop/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. Table 9 Thermal Shutdown Circuit Operation : 150°C (Typ.) Release : 120°C (Typ.) *1. 6. *1 *1 VOUT Pin Voltage VSS level Set value Junction temperature Rush current control circuit The S-1172 Series has a rush current control circuit to control the rush current generated during power-on or when the ON/OFF pin is ON. This circuit limits the rush current (500 mA, Typ.) immediately after power-on or from the ON/OFF pin is ON until the specified time (100 µs min.) which is set internally. Caution The junction temperature drops to 120°C (Typ.) by the operation of thermal shutdown circuit, after stopping regulation, the circuit is released to restart regulation; in this case, note that the period to limit rush current may become shorter (10 µs min.). 16 Seiko Instruments Inc. Rev.1.1_00 HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR S-1172 Series 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 pin (CL) and a capacitor for stabilizing the input between the VIN and VSS pin (CIN), the distance from the capacitors to these pins should be as short as possible. • Note that the output voltage may increase when a series regulator is used at low load current (1.0 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 high temperature. • Generally series regulator may oscillate, depending on the selection of external parts. The following conditions are recommended for this IC. 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 (5) Example of Equivalent Series Resistance vs. Output Current Characteristics (Ta = 25°C) in “ Reference Data”. Input capacitor (CIN) : 4.7 µF or more Output capacitor (CL) : 4.7 µF 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. Note that the voltage regulator may oscillate when the value of the input capacitor is greater than that of the output capacitor. • Ringing may occur when these three conditions below are satisfied. Before selecting an input capacitor, be sure to evaluate sufficiently under the actual usage conditions, including the temperature characteristics. The power supply inductance is high. The load current is 100 mA or more. The difference between the input voltage and the output voltage is close to the value of dropout voltage. • If the output capacitance is small, power supply’s fluctuation and the characteristics of load fluctuation become worse. Sufficiently evaluate the output voltage’s fluctuation with the actual device. • 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 *5 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.
