  • Note 1. There is a possibility with deterioration and destruction of IC when using it exceeding the absolute maximum rating. The absolute maximum rating , Never exceed it. The functional operation is not assured. 2. There is a possibility that it becomes impossible to maintain this performance and reliability IC original when using it exceeding recommended operation voltage. Please use it in recommended operation voltage. 3. Due to restrictions on the package power dissipation, the output current value may not be satisfied. Attention should be paid to the power dissipation of the package when the output current is large or the voltage between Input and Output is high. 4. The output capacitor is required between output and GND to prevent oscillation. 5. The ESR of capacitor must be defined in ESR stability area. It is possible to use a ceramic capacitor without ESR resistance for output. The ceramic capacitor must be used more than 1.0µF and B temperature characteristics. 6. The wire of VDD and GND is required to print full ground plane for noise and stability. 7. The input capacitor must be connected a distance of less than 1cm from input pin. 8. In case the output voltage is above the input voltage, the overcurrent flow by internal parasitic diode from output to input. In such application, the external bypass diode must be connected between output and input pin. 9. Please connect the soft-start capacitor(Cs) more than 0.01 µF with the terminal Cs. 10. The output capacitor and the softstart capacitor must be connected it within the limits a rush current peak level 500mA showed in the typical performance characteristics. 11. When rush current exceeds current limit characteristics, it is restricted with the current limit set up with the chip, an output rise time is uncontrollable by soft-start capacitor. 12. When use connecting VDD and CE, in the case of starting VDD in input rise time longer then the set-up soft-start time, an output rise time is decide by a VDD input rise time. 13. Please do not give the voltage to the terminal Cs. 14. When the voltage of the terminal Cs is higher than the voltage of VDD, it becomes test mode. In that case, there is a possibility that the output voltage becomes unstable. 15. It is able to an unstable operation when you use the capacitor with intense capacitance change The capacitor has the dependency at the power-supply voltage and the temperature. The capacity value changes by the environment used. Please evaluate IC in the set. 16. The overcurrent protection circuit of foldback current limit type is built into this IC. 17. There is a possibility that IC generates heat when the output terminal is short-circuited. However, the thermal shutdown circuit operates, and it will do operation that protects IC. The thermal shutdown circuit is designed only to shut the IC off to prevent thermal runaway. Do not continue to use the IC in an environment where the operation of this circuit is assumed. The characteristic changes depending on the substrate condition. Please evaluate IC in the set. 18. It returns automatically in temperature returned after it shuts down by self-generation of heat. After it returns, it shuts down again by self-generation of heat. It is necessary to change the environment used (IC consumption, temperature) if it operates in upper cycle.

MITSUMI 500mA LDO with soft-start MM3526 Series 19. When VDD rise time is longer than Vout rise time, Vout rise time is decided by VDD rise time. At this time, Vout is may rose more than typical voltage. Please set to soft-start capacitor for the VDD rise time in the slash area shown in Fig. 1. Fig. 1 is common for all the voltage ranks, because soft start time is decided by soft start capacitor and reference voltage. Please choose to a capacitor in consideration of the dispersion .
