LV56841PVD数据手册集成电路（IC）的特殊用途稳压器规格书PDF

描述 Description

The LV56841PVD is a power supply IC suitable for CD receiver system for car audio system. This IC integrates 5 linear voltage regulators, 2 systems of high side power switch, over-current protector, overvoltage protector and over-heat protector . Supply for SW33V outputs is low voltage specification, which enables drastic reduction of power dissipation compared to the existing model. (the package is HZIP15).
