Ultra Low Dropout Linear Regulator
BD3522EFV
General Description BD3522EFV is an ultra low-dropout linear chipset regulator that operates from a very low input supply. It offers ideal performance in low input voltage to low output voltage applications. The input-to-output voltage difference is minimized by using a built-in N-Channel power MOSFET with a maximum ON-Resistance of RON =50mΩ(Max). By lowering the dropout voltage, the regulator achieves high output current of up to (IOUTMAX=4.0A), thereby, reducing conversion loss, making it comparable to a switching regulator and its power transistor, choke coil, and rectifier diode constituents. BD3522EFV is a low-cost design and is available in significantly downsized package profiles. The external resistor allows the entire range of output voltage configurations between 0.65V and 2.7V, while the NRCS (soft start) function enables a controlled output voltage ramp-up, which can be programmed to a requir.
