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 (R ON =50m Ω ) 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%)

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 (28m Ω 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 (0.65 ～ 2.7V) <BD3522EFV>
