TOP GUIDELINES OF ZIRCUIT

With Q1’s base unbiased, all circuitry is off except the LT1054 furthermore-to-minus voltage converter, which draws a a hundred and fiftyμA quiescent recent. When Q1’s base is pulled low, its collector provides electricity to A1 and A2. A1’s output goes superior, turning around the LT1054. the LT1054’s output (Pin 5) heads toward –5V and
