4.3-5.5V 0.55A 1ch LDO - BD3507HFV

The BD3507HFV is suited for power supply for chipset bus. Though small in size, BD3507HFV adopts power PKG with radiation fins, and it therefore can be used for a regulator up to 550mA. Because it adopts Nch MOSFET and can form a ultra low dropout power supply of RON=300mΩ (TYP), BD3507HFV can compose a high-efficiency system, though it is of a linear type power supply. The output voltage can be set by VREF terminal and can be synchronized with other power supply. In addition, it can be used as a high side switch (RON = 300mΩ / lo = 550mA) of low-voltage power supply line.Because ceramic capacitors can be used for output capacitors, BD3507HFV contributes to downsizing and reduced thickness not only of IC but also of sets.
