NJW4182
High Voltage Ultra low current consumption Io=100mA LDO
GENERAL DESCRIPTION
The NJW4182 is a 100mA output Low dropout regulator with high
maximum input voltage, ultra-low current consumption and small package.
Due to the low current consumption, the NJW4182 is suitable
for light load and continuously running applications such as
power management microprocessor, RTC, protection circuit,
security system and so on.

*Overshoot of Output Voltage
Transient fluctuation of output voltage tends to be large compared to other typical regulators because the NJW4182 is
designed with the concept of low current consumption characteristics.
In general, overshoot or undershoot of output voltage is more likely to occur when the following cases.
When input voltage or output current fluctuate sharply
When output capacitance is small
When output load is light
When start up from the condition of narrow voltage difference between an Input and an output.
The NJW4182 can reduce overshoot voltage compared to other low current consumption products by a built-in overshoot
protection (OSP).
However, very large overshoot may occur because of delay of the OSP circuit when the input voltage rises from between 2.0V
and 2.5V.
The value of overshoot varies with composite conditions, please refer the above and check the actual condition.
In addition, the following measures will be mentioned as a method to reduce the overshoot value.
a. By increasing the input and output capacitors to absorb overshoot value.
b. Adjust the rising speed of the input voltage, to avoid rising from between 2.0V and 2.5V.
