Single-chip Type with Built-in FET Switching Regulators  
Output 1.5A or Less  
High-efficiency Step-down Switching Regulator  
with Built-in Power MOSFET  
No.11027EAT38  
BD9123MUV  
Description  
ROHM’s high efficiency step-down switching regulator BD9123MUV is a power supply designed to produce a low voltage  
including 0.85 to 1.2 volts from 5.5/3.3 volts power supply line. Offers high efficiency with our original pulse skip control  
technology and synchronous rectifier. Employs a current mode control system to provide faster transient response to sudden  
change in load.  
Features  
1) Offers fast transient response with current mode PWM control system.  
2) Offers highly efficiency for all load range with synchronous rectifier (Nch/Pch FET)  
and SLLM (Simple Light Load Mode)  
3) Incorporates output voltage inside control function.(3 bit)  
4) Incorporates PGOOD function.  
5) Incorporates soft-start function.  
6) Incorporates thermal protection and ULVO functions.  
7) Incorporates short-current protection circuit with time delay function.  
8) Incorporates shutdown function Icc=0µA(Typ.)  
9) Employs small surface mount package: VQFN016V3030  
Applications  
Power supply for LSI including DSP, Micro computer and ASIC
