Operational Notes 1. Absolute maximum ratings Exceeding the absolute maximum rating for supply voltage, oper ating temperature or other parameters can result in damages to or destruction of the chip. In this event it also becomes impossible to det ermine the cause of the damage (e.g. short circuit, open circuit, etc). Therefore, if any specia l mode is being considered with values expected to exceed the absolute maximum ratings, implementing physical safety measures, such as adding fuses, should be considered. 2. The electrical characteristics given in this specification may be influenced by conditions such as temperature, supply voltage and external components. Transient characteristics should be sufficiently verified.. 3. GND electric potential Keep the GND pin potentia l at the lowest (minimum) level under any oper ating condition. Furthermore, ensure that, including the transient, none of the pin’s voltages are less than the GND pin voltage. 4. Ground wiring pattern When both a small-signal GND and a high curr ent GND are present, single-point gr ounding (at the set standard point) is recommended. This in order to separate the small-signal and high current patterns and to ensure that voltage changes stemming from the wiring resistance and high current do not cause any voltage change in the small-signal GND. Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external component GND. 5. Inter-pin shorting and mounting errors Ensure that when mounting the IC on the PCB the direction and position are correct. Incorrect mounting may result in damaging the IC. Also, shorts caused by dust entering betw een the output, input and GND pin may result in damaging the IC. 6. Operation Under Str ong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 7. Inspection using the set board The IC needs to be discharged after each inspection process as, while using the set board for inspection, connecting a capacitor to a low-impedance pin may cause stress to the IC. As a protection from static electricity, ensure that the assembly setup is grounded and take sufficient caution with tr ansportation and storage. Also, make sure to turn off the power supply when connecting and disconnecting the inspection equipment. 8. Power dissipation (Pd) Should by any chance the power dissipation rating be exceed ed the rise in temperature of the chip may result in deterioration of the properties of the chip. The absolute maximum rating of the Pd stated in this specification is when the IC is mounted on a 70mm X 70mm X 1.6mm glass epoxy board. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating. 9. Thermal design The power dissipation under actual oper ating conditions should be taken into consideration and a sufficient margin should be allowed for in the thermal design. On the reverse side of the package this product has an exposed heat pad for improving the heat dissipation. Use both the front and reverse side of the PCB to increase the heat dissipation pattern as far as possible. The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current. Therefore, when actually using the chip, ensure that the gener ated heat does not exceed the Pd rating.

Vcc pin Insert a capacitor with a capacitance of 1μF or higher between the Vcc and GND pins. Choose the capacitance according to the line between the power smoothing circuit and the V cc pin. Selection of the ca pacitance also depends on the application. Verify the application and allow for sufficient margins in the design. We recommend using a capacitor with excellent voltage and temperature characteristics. Electric capacitance Ceramic capacitors, Low ESR capacitor IC

Output pin In order to prevent oscillation, a capacitor needs to be placed between the output pin and GND pin. We recommend a capacitor with a capacitance of more than 1 μF. Electrolytic, tantalum and ceramic capacitors can be used. When selecting the capacitor ensure that the capacitance of more than 1 μF is maintained at the intended applied voltage and temperature range. Due to changes in temperature, the capacitance can fluctuate possibly resulting in oscillation. For selection of the capacitor refer to the Cout ESR vs. Io. The stable operation range given in the reference data is based on the standalone IC and resistive load. For actual applications the stable operating range is influenced by the PCB impedance, input supply impedance and load impedance. Theref ore verification of the final operating environment is needed. When selecting a ceramic type capacitor, we recommend using X5R, X7R or better with excellent temperature and DC-biasing characteristics and high voltage tolerance. Also, in case of rapidly changing input voltage and load current, select the capacitance in accordance with verifying that the actual application meets with the required specification. 12. Rapid variation in Vcc voltage and load current In case of a rapidly changing input voltage, transients in the output voltage might occur due to the use of a MOSFET as output transistor. Although the actual application might be the cause of the transients, the IC input voltage, output current and temperature are also possible causes. In case prob lems arise within the actual operating range, use countermeasures such as adjusting the output capacitance. 13. Minute variation in output voltage In case of using an application susceptible to minute changes to the output voltage due to noise, changes in input and load current, etc., use countermeasures such as implementing filters. 14. Over current protection circuit (OCP) This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit.

Thermal shutdown circuit (TSD) This IC incorporates and integrated thermal shutdown circuit to prevent heat damage to the IC. Normal operation should be within the power dissipation rating, if however the rating is exceeded for a continued period, the junction temperature (Tj) will rise and the TSD circuit will be activated and turn all output pins OFF. After the Tj falls below the TSD threshold the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. 16. In some applications, the Vcc and pin potential might be reversed, possibly resulting in circuit internal damage or damage to the elements. For example, while the external capacitor is charged, the Vcc shorts to the GND. Use a capacitor with a capacitance with less than 1000 μF. We also recommend using reverse polarity diodes in series or a bypass between all pins and the Vcc pin. 17. This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P/N junctions are formed at the intersection of these P layers with the N layers of other elements to create a variety of parasitic elements. For example, in case a resistor and a transistor are connected to the pins as shown in the figure below then: ○ The P/N junction functions as a parasitic diode when GND > pin A for the resistor, or GND > pin B for the transistor. ○ Also, when GND > pin B for the transistor (NPN), the parasitic diode described above combines with the N layer of the other adjacent elements to operate as a parasitic NPN transistor. Parasitic diodes inevitably occur in the structure of the IC. Their operation can result in mutual interference between circuits and can cause malfunctions and, in turn, physical dam age to or destruction of the chip. Therefore do not employ any method in which parasitic diodes can operate such as applying a voltage to an input pin that is lower than the (P substrate) GND.
