This article provide two programs which can get the second negative output from the power level of a main low-dropout regulator.

本文给出了两种从一个主降压稳压器的功率级得出一个第二负输出的方案，这两种方案具有广泛的实用价值。

When we use low-dropout switching power switching converter to reduce positive input voltage, we usually need an extra low - power negative output voltage.

在采用降压开关功率开关转换器降低正输入电压的同时，通常还需要一个额外的低功率负输出电压。

It turns out that the two positive links mentioned above are roughly offset by the two negative links — the net effect on U.S. output and employment is small.

结果发现，上面提到的两条正面关联被另两条负面关联大致抵消，所以人民币升值对美国产出和就业产生的净效应并不大。

As was demonstrated in the 1970s, even small increases in marginal tax rates have a substantial negative impact on output.

The Great Depression also began with a financial crisis but saw high growth rates following contractionary years, and the output lost in negative years was eventually regained through higher subsequent growth.
