If the temperature exceeds the maximum junction temperature Tjmax, deterioration or damage may occur. Implement proper thermal designs to ensure that power dissipation is within the permissible range in order to prevent instantaneous damage resulting from heat and maintain the reliability of the IC for long-term operation. The following method is used to calculate the power consumption Pc (W). Pc = (Vcc – Vo) × Io + Vcc × Icca Vcc : Input voltage Power dissipation Pd ≧ Pc Vo : Output current I : Load current O The load current Io is calculated: Icca : Circuit current Pd − Vcc × Icca Io ≦ Vcc − Vo Calculation Example: Vcc = 6.0 V and Vo = 5.0 V at Ta = 85°C 0.676 − 6.0 × Icca θja = 96.2°C/W → −10.4mW/°C Io≦ 6.0 − 5.0 25°C = 1300mW → 85°C = 676mW Io ≦ 550mA (Icca ≈ 20mA) www.rohm.com TSZ02201-0R6R0A600120-1-2 © 2012 ROHM Co., Ltd.

BAxxBC0 Series BAxxBC0W Series BA00BC0WCP-V5 Datasheet Refer to the above and implement proper thermal designs so that the IC will not be used under excessive power dissipation conditions under the entire operating temperature range. The power consumption Pc of the IC in the event of shorting (i.e. the Vo and GND pins are shorted) can be obtained from the following equation: Pc = Vcc × (Icca + Ishort) (Ishort: short current). ●Peripheral Circuit Considerations • Vcc pin Insert a capacitor (0.33μF approx.) between V and GND. CC The capacitance will vary depending on the application. Use a suitable capacitance and implement designs with sufficient margins. • GND pin Verify that there is no potential difference between the ground of the application board and the IC. If there is a potential difference, the set voltage will not be output accurately, resulting in unstable IC operation. Therefore, lower the impedance by designing the ground pattern as wide and as short as possible. • CTL terminal CTL 27kΩ 2kΩ The CTL terminal turns on at an operating power supply voltage of 2.0 V or higher and turns off at 0.8 V or lower. 31kΩ There is no particular order when turning the power supply and CTL terminals on or off. Fig.20 Input Equivalent Circuit ●Vo Terminal Insert a capacitor between the Vo and GND pins in order to prevent output oscillation. 10.0 Oscillation region 2.0 OUT ] Ω 1.0 R [ S 0.5 IC E Stable region 22 μF 0.2 0.1 0.075 0.05 Oscillation region 0 200 400 600 800 1000 Io [mA] Fig.21 Output Equivalent Circuit Fig.22 ESR vs. I (22μF) O The capacitance may vary greatly with temperature changes, thus making it impossible to completely prevent oscillation. Therefore, use a tantalum aluminum electrolytic capacitor with a low ESR (Equivalent Serial Resistance). The output will oscillate if the ESR is too high or too low, so refer to the ESR characteristics in Fig.22 and operate the IC within the stable region. Use a capacitor within a capacitance between 22μF and 1,000μF. Below figure, it is ESR-to-Io stability Area characteristics, measured by 22μＦ-ceramic-capacitor and resistor connected in series. This characteristic is not equal value perfectly to 22µＦ-aluminum electrolytic capacitor in order to measurement method. Note, however, that the stable range suggested in the figure depends on the IC and the resistance load involved, and can vary with the board’s wiring impedance, input impedance, and/or load impedance. Therefore, be certain to ascertain the final status of these items for actual use. Keep capacitor capacitance within a range of 22µF to 1000μF. It is also recommended that a 0.33μF bypass capacitor be connected as close to the input pin-GND as location possible. However, in situations such as rapid fluctuation of the input voltage or the load, please check the operation in real application to determine proper capacitance. www.rohm.com TSZ02201-0R6R0A600120-1-2 © 2012 ROHM Co., Ltd.

BAxxBC0 Series BAxxBC0W Series BA00BC0WCP-V5 Datasheet ●Operational Notes 1. Absolute maximum ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses. 2. GND voltage The potential of GND pin must be minimum potential in all operating conditions. 3. Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. 4. Inter-pin shorts and mounting errors Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection error or if pins are shorted together. 5. Actions in strong electromagnetic field Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to malfunction. 6. Testing on application boards When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress. Always discharge capacitors after each process or step. Always turn the IC's power supply off before connecting it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an antistatic measure. Use similar precaution when transporting or storing the IC. 7. Regarding input pin of the IC 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, creating a parasitic diode or transistor. For example, the relation between each potential is as follows: When GND > PIN A and GND > PIN B, the P-N junction operates as a parasitic diode. When GND > PIN B, the P-N junction operates as a parasitic transistor. Parasitic diodes can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used. 8. Ground Wiring Pattern When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the ground potential of application so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change the GND wiring pattern of any external components, either. 9. Thermal shutdown circuit The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or guarantee its operation. Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation of this circuit is assumed. 10. Overcurrent Protection Circuit An overcurrent protection circuit is incorporated in order to prevention destruction due to short-time overload currents. Continued use of the protection circuits should be avoided. Please note that the current increases negatively impact the temperature. 11. Damage to the internal circuit or element may occur when the polarity of the Vcc pin is opposite to that of the other pins in applications. (I.e. Vcc is shorted with the GND pin while an external capacitor is charged.) Use a maximum capacitance of 1000μF for the output pins. Inserting a diode to prevent back-current flow in series with Vcc or bypass diodes between Vcc and each pin is recommended. www.rohm.com TSZ02201-0R6R0A600120-1-2 © 2012 ROHM Co., Ltd.

ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which a failure or malfunction of our Products may cause. The following are examples of safety measures: [a] Installation of protection circuits or other protective devices to improve system safety [b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure 3. Our Products are designed and manufactured for use under standard conditions and not under any special or extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any special or extraordinary environments or conditions. If you intend to use our Products under any special or extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: [a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents [b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust [c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves [e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items [f] Sealing or coating our Products with resin or other coating materials [g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning residue after soldering [h] Use of the Products in places subject to dew condensation 4. The Products are not subject to radiation-proof design. 5. Please verify and confirm characteristics of the final or mounted products in using the Products. 6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied, confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability. 7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual ambient temperature. 8. Confirm that operation temperature is within the specified range described in the product specification. 9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in this document. Precaution for Mounting / Circuit board design 1.
