LV5810M
Step-down Switching Regulator
Overview
LV5810M is a 1ch step-down switching regulator. 0.13
Ω FET is incorporated on the upper side to achieve high-efficiency
operation for large output current. Low-heat resistance and compact-package MFP8 (225mil) 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 100
μA 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.
Functions
