Ultra Low Dropout Linear Regulator
BD35221EFV
General Description BD35221EFV 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. It is a low-cost design and is available in significantly downsized package profiles.
