S-1170 Series www.ablic.com www.ablicinc.com HIGH RIPPLE-REJECTION AND LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.4.1_02 © ABLIC Inc., 2003-2015 The S-1170 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, a built-in overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor, and a built-in thermal shutdown circuit prevents damage caused by the heat. 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 SOT-89-5 and 6-Pin HSON(A) packages realize high-density mounting.  Features  Output voltage:  Output voltage accuracy:  Dropout voltage:  Current consumption:  Output current:  Input and output capacitors:  Ripple rejection:  Built-in overcurrent protection circuit:  Built-in thermal shutdown circuit:  Built-in ON/OFF circuit:  Operation temperature range:  Lead-free, Sn 100%, halogen-free*2 1.5 V to 5.5 V, selectable in 0.1 V step 1.0% 120 mV typ.

Perform thorough evaluation using the actual application to set the constant.  Condition of Application Input capacitor (CIN): Output capacitor (CL): ESR of output capacitor: 4.7 F or more 4.7 F or more 0.5  or less Caution Generally a series regulator may cause oscillation, depending on the selection of external parts. Check that no oscillation occurs with the application using the above capacitor.  Selection of Input and Output Capacitors (CIN, CL) The S-1170 Series requires an output capacitor between the VOUT pin and the VSS pin for phase compensation. A ceramic capacitor with a capacitance of 4.7 F or more provides a stable operation in all temperature ranges. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must be 4.7 F or more, and the ESR must be 0.5  or less. The output overshoot and undershoot values, which are transient response characteristics, vary depending on the output capacitor value. The required capacitance value for the input capacitor differs depending on the application. The recommended value for an application is CIN  4.7 F and CL  4.7 F, however, perform a thorough evaluation using the actual device, including evaluation of temperature characteristics. 11 HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.4.1_02 S-1170 Series  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. Low ESR A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1170 Series enables use of a low ESR capacitor, such as a ceramic capacitor, for the output-side capacitor (CL). A capacitor whose ESR is 0.5  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.

Basic operation Figure 12 shows the block diagram of the S-1170 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-1170 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 LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.4.1_02 S-1170 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 hundreds k 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.

Thermal shutdown circuit The S-1170 Series implements a thermal shutdown circuit to protect the device from damage due to overheating. When the junction temperature rises to 150C (typ.), the thermal shutdown circuit operates and the regulator operation stops. When the junction temperature drops to 120C (typ.), the thermal shutdown circuit is released and the regulator operation resumes. If the thermal shutdown circuit starts operating due to self-heating, the regulator operation stops and the output voltage falls. When the regulator operation has stopped, no self-heat is generated and the temperature of the IC is lowered. When the temperature has dropped, the thermal shutdown circuit is released, the regulator operation resumes, and self-heat is generated again. By repeating this procedure, the output voltage waveform forms pulses. Stop or restart of regulation continues unless decreasing either or both of the input voltage and the output current in order to reduce the internal power consumption, or decreasing the ambient temperature.

Set value HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.4.1_02 S-1170 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).  Note that the output voltage may increase due to the leakage current from an output driver even if the ON/OFF pin is at OFF level when a series regulator is used at high temperature.  Generally a series regulator may cause oscillation, depending on the selection of external parts. The following conditions are recommended for the S-1170 Series. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Input capacitor (CIN): 4.7 F or more Output capacitor (CL): 4.7 F or more Equivalent series resistance (ESR): 0.5  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 5 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. 17 HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.4.1_02 S-1170 Series  Characteristics (Typical Data) (1) Output voltage vs. Output current (when load current increases) S-1170B30 (Ta  25C) 3.5 1.8 1.6 1.4 1.2 1.0 0.8 0.6 0.4 0.2 0 3.0 2.5 VOUT [V] VOUT [V] S-1170B15 (Ta  25C) VIN  2.0 V 2.5 V 6.5 V VIN  3.5 V 2.0 4.0 V 1.5 6.5 V 1.0 0.5 0 0 200 400 800 600 1000 1200 0 200 IOUT [mA] 400 800 600 1000 1200 IOUT [mA] S-1170B50 (Ta  25C) 6 5 VOUT [V] 4 VIN  5.5 V 6.0 V 6.5 V 3 2 1 0 0 200 400 600 800 1000 1200 Remark In determining the output current, attention should be paid to the following. 1.
