BD9122GUL  
General Description  
Key Specifications  
Input Voltage Range:  
Output Voltage Range:  
Output Current:  
The BD9122GUL is ROHM’s high efficiency step-down  
switching regulator designed to produce a voltage as  
low as 1V from a supply voltage of 3.3V or 5V. It offers  
high efficiency by using pulse skip control technology  
and synchronous switches, and provides faster  
transient response to sudden load changes by  
implementing current mode control.
