Title: Stabilized power supply circuit
Inventor: NIWA MASAHISA
IPC: G05F3/30
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a stabilized power supply circuit which can be surely operated even when gradually increasing an input voltage. SOLUTION: A pnp type transistor Q1 is inserted between input and output terminals. An output voltage Vcc is divided by voltage dividing resistors R1, R21 and R22 and a detected voltage Vref at the node of the resistors R1 and R21 is compared with a reference voltage Vb. An error amplifier EA adjusts the loss amount of the transistor Q1 so as to keep constant the output voltage Vcc corresponding to the difference between the detected voltage Vref and the reference voltage Vb. Resistors RA and RB divide an input voltage Vin and generate a comparative voltage Va. During the period when the comparative voltage Va is lower than the reference voltage Vb, a voltage comparator circuit CP turns on a switching element SW and increases the ratio of the detected voltage Vref in respect to the output voltage Vcc.  Namely, when the input voltage Vin is low, the target value of the output voltage Vcc is practically reduced.
