数据表中:
7.4.1 Operation With 16 V ≥ VIN > VOUT(TARGET) + 1 V
The device operates if the input voltage is equal to, or exceeds VOUT(TARGET) + 1 V. At input voltages below the
minimum VIN requirement, the devices does not operate correctly, and output voltage may not reach target value.
这段话的意思是否是说:输入电压必须大于输出电压1V以上,输出电压才能达到输出值。也就是电压降至少1V才能正常工作。
这是否和低压差矛盾,最低电压差为310mV(Dropout Voltage: Typically 310 mV at 500-mA load,and 1 mV at 100-µA load.) 。

在备注处有说明: (2) Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below the value measured with a 1-V differential.

这句话我也注意到了,没看懂是什么意思?
