Finally, the positive and negative output voltage difference to the motor driver chip motor positive decision.

最后，电压差的正负输出到电机驱动芯片决定电机的正反转。

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。

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.
