Rev.1.1_00 ULTRA LOW CURRENT CONSUMPTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR S-1206 Series The S-1206 Series is a positive voltage regulator with ultra low current consumption, low dropout voltage, high output voltage accuracy, and 250 mA output current developed based on CMOS technology. I/O capacitors are as small as 0.1 µF. S-1206 Series operates at ultra low current consumption of 1.0 µA (typ.). The built-in low-on-resistance transistor realizes low dropout voltage and high output current. A built-in overcurrent protection circuit prevents the load current from exceeding the current capacitance of the output transistor. Three packages, SOT-23-3, SOT-89-3, and SNT-6A(H), are available. Compared with voltage regulators using a conventional CMOS process, more types of capacitors, including small I/O capacitors, can be used with the S-1206 Series. The S-1206 Series features ultra-low current consumption and comes in a small package, making them most suitable for portable equipment. Features • Output voltage : 1.2 to 5.2 V, selectable in 0.05 V steps. • Low equivalent series resistance capacitor can be used : A ceramic capacitor of 0.1 µF or more can be used for the I/O capacitor. • Wide input voltage range : 1.7 to 6.5 V • High-accuracy output voltage : ±1.0% (1.2 to 1.45 V output product : ±15 mV) • Low dropout voltage : 150 mV typ.

Check that Selection of Input Capacitor (CIN) and Output Capacitor (CL) The S-1206 Series requires an output capacitor between the VOUT pin and VSS pin for phase compensation. Operation is stabilized by a ceramic capacitor with an output capacitance of 0.1 µF or more in the entire temperature range. However, when using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor with a capacitance of 0.1 µF or more less is required. The value of the output overshoot or undershoot transient response varies depending on the value of the output capacitor. The required capacitance of the input capacitor differs depending on the application. The recommended value for an application is 0.1 µF or more for CIN and 0.1 µF or more for CL; however, when selecting these capacitors, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.

Output Transistor The S-1206 Series uses a low-on-resistance P-channel MOS FET as the output transistor. Be sure that VOUT does not exceed VIN + 0.3 V to prevent the IC from being damaged due to inverse current flowing from the VOUT pin through a parasitic diode to the VIN pin. 12 Seiko Instruments Inc. ULTRA LOW CURRENT CONSUMPTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.1.1_00 S-1206 Series 3. Overcurrent protection circuit An overcurrent protection circuit with the characteristics shown in (1) Output Voltage vs. Output Current (Ta = 25 °C) in “ Characteristics (Typical Data)” is built into the S-1206 Series to protect output transistors from excessive output current and short circuiting between the VOUT and VSS pins. The current when output short circuiting (ISHORT) is internally set to 100 mA (typ.) (VOUT ≥ 2.3 V) and the output voltage returns to the normal value when short circuiting has been released. Note that the overcurrent protection circuit does not function as a circuit for thermal protection. Therefore, in cases where a short circuiting status may continue for a long time, pay sufficient attention to the input voltage and load current conditions so that the loss of the IC will not exceed power dissipation of the package under use conditions, including short circuiting conditions.

When mounting an output capacitor between the VOUT pin and VSS pin (CL) and a capacitor for stabilizing the input between the VIN pin and VSS pin (CIN), the distance from the capacitors to these pins should be as short as possible. • Note that the output voltage may generally increase when a series regulator is used at low load current (10 µA or less). • Note that the output voltage may generally increase due to driver leakage when a series regulator is used at high temperatures. • Generally a series regulator may cause oscillation, 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 evaluation of temperature characteristics. For the equivalent series resistance (RESR) of the output capacitor, refer to (5) Equivalent Series Resistance vs. Output Current Characteristics Example (Ta = 25°C) in “ Reference Data”. Input capacitor (CIN) : Output capacitor (CL) : 0.1 µF or more 0.1 µF or more Use an I/O capacitor with good temperature characteristics (conforming to the ceramic capacitor EIA X5R (JIS B) 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. • If the output capacitance is small, the power supply fluctuation and load fluctuation characteristics become worse. Sufficiently evaluate the output voltage fluctuation with the actual device. • If the power supply suddenly increases sharply when the output capacitance is small, a momentary overshoot may be output. It is therefore important to sufficiently evaluate the output voltage at power application in the actual device. • The application conditions for the input voltage, output voltage, and 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. • 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. 14 Seiko Instruments Inc. ULTRA LOW CURRENT CONSUMPTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.1.1_00 S-1206 Series Characteristics (Typical Data) (1) Output Voltage vs. Output Current (Ta = 25 °C) S-1206B12 1.4 1.2 1.0 0.8 0.6 0.4 0.2 VOUT [V] 1.5 V 1.7 V 0 VOUT [V] VIN = 2.2 V 3.2 V 6.5 V S-1206B30 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0 0 100 3.3 V 4.0 V VIN = 3.5 V 5.0 V 6.5 V 0 100 200 300 400 500 600 700 IOUT [mA] 200 300 400 500 600 700 IOUT [mA] S-1206B50 6 5 VOUT [V] VIN = 5.5 V 6.0 V 5.3 V 6.5 V 4 3 2 1 0 0 100 Remark In determining the output current, attention should be paid to the following. 1.
