TECHNICAL NOTE High-performance Regulator IC Series for PCs Ultra Low Dropout Linear Regulators for PC BD3550HFN, BD3551HFN, BD3552HFN (0.5～2.0A) - Description BD3550HFN,BD3551HFN,BD3552HFN 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 <BD3552HFN>) level. By lowering the dropout voltage in this way, the regulator realizes high current output (Iomax=2.0A <BD3552HFN>) with reduced conversion loss, and thereby obviates the switching...
