Abstract
PURPOSE: To give an optional divided voltage and to the output to lower the output impedance, by branching the current flowed to a PNP transistor of a push-pull buffer and providing a branching transistor to which the branched current is flowed.
CONSTITUTION: An input voltage Vi is applied to a series circuit of diodes Ds 1 and 2 connected forward between resistances Rs 1 and 2. A divided anode voltage of the D1 is given to the base of an NPN transistor (TR)Q1, and the cathode voltage of the D2 is given to the base of a PNPTRQ2. Emitters of TRs Q1 and Q2 forming a push-pull buffer are connected to an output OUT to generate a voltage-divided output. The current flowed to the TRQ2 is branched by an NPNTRQ3 of a high current amplification factor. Most of a load current Il due to a load Zl connected to the terminal OUT is flowed to the TRQ3 to give an optional divided voltage to the output and to lower the output impedance.
