*1 With the measurement circuit of 4-4. Unless otherwise mentioned in these specifications, input
and output shall be rated and ambient temperature shall be 25°C±5°C.
*2 Minimum input voltage varies according to the ambient temperature. Refer to 7-5.
*3 Input: For variation of input voltage = min to max.
Load: For variation of output current = 0 to rated.
Temperature: For variation of ambient temperature = -40 to Tamax.
For within ambient temperature range with 100% load at temperature derating of 4-3.
A two output product is when + output current and – output current are equal.
*4 Measured frequency bandwidth 20MHz. At both ends of external capacitor (C2, or C4,C5).
