Overview
Step-down Switching
Regulator
LV58082MX is a 1ch step-down switching
regulator. 0.3Ω FET is incorporated on the upper side to achieve high-efficiency operation for large output current. Low-heat resistance and compact-package MFP8 (200mil) employed. Current mode control type, with superior load current response and easy phase compensation EN pin, allowing the standby mode with the current drain of 100μA 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
0.4A 1ch step-down switching
regulator Wide input dynamic range ( to 28V) Standby mode Over-current protection Thermal shutdown
Reference voltage: 0.8V Fixed frequency: 370kHz Soft start Compact package: MFP8 (200mil) with Heat sink
