High Performance Regulators for PCs Nch FET Ultra LDO for PC Chipsets BD3508MUV Nch FET Ultra LDO for PC Chipsets with Power Good BD3509MUV No.10030ECT22 ●Description The BD3508MUV / BD3509MUV ultra low-dropout linear chipset regulator operates from a very low input supply, and offers ideal performance in low input voltage to low output voltage applications. It incorporates a built-in N-MOSFET power transistor to minimize the input-to-output voltage differential to the ON resistance (RON MAX=100mΩ/50mΩ) level. By lowering the dropout voltage in this way, the regulator realizes high current output (Iomax=3.0A/4.0A) with reduced conversion loss, and thereby obviates the switching regulator and its power transistor, choke coil, and rectifier diode.
