To reduce a size, a weight, and costs of a voltage stabilizing device that is provided in a vehicle having an idling stop function and that outputs a power source voltage to a predetermined on-vehicle electronic apparatus on the basis of an input voltage from a battery when an engine is re-started by the idling stop function.SOLUTION: A voltage stabilizing device according to the present invention comprises: a first stabilizing circuit by which a stabilized voltage in which an input voltage is stabilized is output to an on-vehicle electronic apparatus of a first class; and a second stabilizing circuit by which a stabilized voltage in which the input voltage is stabilized is output to an on-vehicle electronic apparatus of a second class. The second stabilizing circuit is lower in boosting capability than the first stabilizing circuit.SELECTED DRAWING: Figure 3
【課題】アイドリングストップ機能を有する車両に設けられ、アイドリングストップ機能によりエンジンが再始動される際にバッテリからの入力電圧に基づいて所定の車載電子機器に電源電圧を出力する電圧安定化装置について、装置の小型軽量化、及びコストの削減を図る。【解決手段】本発明に係る電圧安定化装置は、入力電圧を安定化した安定化電圧を第一種の車載電子機器に出力する第一安定化回路と、入力電圧を安定化した安定化電圧を第二種の車載電子機器に出力する第二安定化回路と、を備え、第二安定化回路は、第一安定化回路よりも昇圧能力が低いものである。【選択図】図3
