High Performance Regulators for PCs

Nch FET Ultra LDO

for PC Chipsets

BD3507HFV

No.10030EAT31

●Description

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 LDO power supply of R_ON=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 (R_ON= 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.

●Features

1) Built-in high-accuracy buffer circuit (can be set to 0.65-2.7V)

2) Adoption of ceramic capacitors

3) Built-in enable function (0μA at standby)

4) Built-in current limiting circuit (550mA Max)

5) Built-in under voltage lockout circuit (UVLO)

6) Built-in thermal shutdown circuit (TSD)

7) Adoption of ultra-small-size high-power HVSOF6 package (3.0 x 1.6 x 0.75 mm)

●Applications

Notebook PC, desktop PC, digital camera, digital home appliances
