Low dropout voltage regulator The low dropout voltage regulator is a voltage regulator featuring a low dropout voltage characteristic due to its internal low ON-resistance characteristic transistors. 2. Low ESR ESR is the abbreviation for Equivalent Series Resistance. The low ESR output capacitor (CL) can be used in the S-814 Series. 3.

Basic operation Rev.2.1_00 Figure 12 shows the block diagram of the S-814 Series. The error amplifier compares a reference voltage Vref with part of the output voltage divided by the feedback resistors Rs and Rf.

Output transistor The S-814 Series uses a low on-resistance 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 broken due to inverse current flowing from VOUT pin through a parasitic diode to VIN pin. 12 Seiko Instruments Inc. Rev.2.1_00 LOW DROPOUT CMOS VOLTAGE REGULATOR S-814 Series 3. ON/OFF pin (Shutdown pin) This pin starts and stops the regulator. When the shutdown pin is switched to the shutdown level, the operation of all internal circuits stops, the built-in Pch MOSFET output transistor between VIN pin and VOUT pin is shutdown, allowing current consumption to be drastically reduced. The VOUT pin enters the Vss level due to internally divided resistance of several MΩ between VOUT pin and VSS pin. Furthermore, 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 state. In addition, please note that current consumption increases if a voltage of 0.3 V to VIN−0.3 V is applied to the shutdown pin. When the ON/OFF pin is not used, connect it to the VIN pin in case of the product type is ‘”A” and to the VSS pin in case of “B”.

Short-circuit protection circuit The S-814 Series incorporates a short-circuit protection circuit to protect the output transistor against short-circuiting between VOUT pin and VSS pin. The short-circuit protection circuit controls output current as shown in “1. Output voltage vs. Output current (When load current increases)” curve in “ Characteristics”, and prevents output current of approx. 70 mA or more from flowing even if VOUT pin and VSS pin are shorted. However, the shortcircuit protection circuit does not protect thermal shutdown. Be sure that input voltage and load current do not exceed the specified power dissipation level. When output current is large and a difference between input and output voltages is large even if not shorted, the short-circuit protection circuit may start functioning and the output current may be controlled to the specified amperage. For details, refer to “3. Maximum output current vs. Input voltage” curve in “ Characteristics”. Seiko Instruments Inc. 13 LOW DROPOUT CMOS VOLTAGE REGULATOR S-814 Series Selection of Output Capacitor (CL) Rev.2.1_00 Mount an output capacitor between VOUT pin and VSS pin for phase compensation. The S-814 Series enables customers to use a ceramic capacitor as well as a tantalum or an aluminum electrolytic capacitor. • A ceramic capacitor or an OS capacitor: Use a capacitor of 0.47 μF or more. • A tantalum or an aluminum electrolytic capacitor: Use a capacitor of 0.47 μF or more and ESR of 10 Ω or less. Pay special attention not to cause an oscillation due to an increase in ESR at low temperatures, when you use the aluminum electrolytic capacitor. Evaluate the capacitor taking into consideration its performance including temperature characteristics. Overshoot and undershoot characteristics differ depending upon the type of the output capacitor you select. Refer to “CL dependencies of overshoot” and “CL dependencies of undershoot” in “ Transient Response Characteristics”. Precautions • Wiring patterns for VIN pin, VOUT pin and GND pin should be designed so that the impedance is low. When mounting an output capacitor, the distance from the capacitor to the VOUT pin and the VSS pin should be as short as possible. • Note that output voltage may increase when a series regulator is used at low load current (Less than 10 μA). • 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 to select the series regulator. 0.47 μF or more Output capacitor (CL): Equivalent Series Resistance (ESR): 10 Ω or less Input series resistance (RIN): 10 Ω or less • The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small or an input capacitor is not connected. • The application conditions for input voltage and load current do not exceed the power dissipation level of the package. • In determining the output current, attention should be paid to the output current value specified and footnote *3 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-814 Series 1.
