LV5813TT
Bi-CMOS IC
Step-down Switching Regulator
Overview
LV5813TT is 1ch step down switching regulator. 0.25Ω FET is incorporated on the upper side to achieve high-efficiency
operation for large output current. Compact-package MSOP8 (150mil) employed. Current mode control type, with
superior load current response and easy phase compensation. ON/OFF pin, allowing the standby mode with the current
drain of 90μA or less. Pulse-by-pulse over-current protection and overheat protection available for protection of load
devices. Soft start pin to be provided with a capacitance for soft start.
