1.25V to VCC-1V, 4A 1ch  
Ultra Low Dropout Linear Regulator  
BD35221EFV  
General Description  
Key Specifications  
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.
