BD35222EFV

TECHNICAL NOTE High-performance Regulator IC Series for PCs Ultra Low Dropout Linear Regulators(4A) for Desktop PC BD3522EFV, BD35221EFV, BD35222EFV ● Description BD3522EFV / BD35221EFV / BD35222EFV 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=50mΩ) level. By lowering the dropout voltage in this way, the regulator realizes high current output (Iomax=4.0A) with reduced conversion loss, and thereby obviates the switching regulator and its power transistor, choke coil, and rectifier diode. Thus, BD3522EFV / BD35221EFV / BD35222EFV designed to enable significant package profile downsizing and cost reduction. In BD3522EFV, an external resistor allows the entire range of output voltage configurations between 0.65 and 2.7V, while the NRCS...
