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 (soft  
start) function enables a controlled output voltage ramp-up, which can be programmed to whatever power supply sequence  
is required.  
Features  
1) Internal high-precision reference voltage circuit(0.65V±1%)  
2) Internal high-precision output voltage circuit <BD35221EFV/BD35222EFV>  
3) Built-in VCC undervoltage lockout circuit (VCC=3.80V)  
4) NRCS (soft start) function reduces the magnitude of in-rush current  
5) Internal Nch MOSFET driver offers low ON resistance (28mΩ typ)  
6) Built-in short circuit protection (SCP)  
7) Built-in current limit circuit (4.0A min)  
8) Built-in thermal shutdown (TSD) circuit  
9) Variable output (0.652.7V) <BD3522EFV>  
10) High-power package HTSSOP-B20 : 6.5mm x 6.4mm x 1.0mm  
11) Tracking function
