BD3508EKN
● Description The BD3508EKN 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=65mΩ) level.
By lowering the dropout voltage in this way, the
regulator realizes high current output (Iomax=3.
0A) with reduced conversion loss, and thereby obviates the switching
regulator and its power
transistor, choke coil, and rectifier diode.
