Title: Constant voltage circuit
Inventor: OSATO YUTAKA
IPC: G05F3/22
Filed: 1985-12-26
Abstract: PURPOSE:To obtain a constant voltage circuit having the low power consumption by securing an output type where the emitter followers of an NPN transistor TR and a PNP TR are connected with each other. CONSTITUTION:An NPN transistor TRQ6 and a PNP TRQ8 supply the bias current to an NPN TRQ7 and a PNP TRQ9 respectively. If a current Iin is supplied from an output terminal 1 and a current IB is supplied from the base of the TRQ9, the change component DELTAIB of the base current is equal to (dIB/ dIC)DELTAIC. Where DELTAIC is equal to the current Iin and dIB/dIC is equal to hFE of the TRQ9. Therefore DELTAIB=Iin/hFE is satisfied and the current Iin supplied from the terminal 1 is controlled by the current I/hFE supplied. Thus the current supplied from a constant current source IC2 is reduced.
