TECHNICAL NOTE High-performance Regulator IC Series for PCs Ultra Low Dropout Linear Regulators for PC Chipsets with Power Good BD3512MUV (3A) ● Description The BD3512MUV 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=100mΩ) 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.
