Ordering number : ENA2120 LV58063MC Bi-CMOS LSI Step-down Switching Regulator Overview http://onsemi.com LV58063MC is a 1ch step-down switching regulator.
0.13Ω FET is incorporated on the upper side to achieve high-efficiency operation for large output current.
Low-heat resistance and compact-package SOP8L (200mil) employed.
Current mode control gives superior load current response with easy phase compensation.
EN pin, allowing the standby mode with the current drain of 70μA.
