Bi-CMOS IC
LV5808MXZ ^{Step-down Switching}
Regulator
Overview
LV5808MXZ 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 ON/OFF pin, allowing the
standby mode with the current drain of 100μA 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
• 2A 1ch step-down switching regulator
• Wide input dynamic range (to 28V)
• High efficiency (90% IOUT = 1A, VIN = 12V, VO = 5V)
• Standby mode
• Over-current protection
• Thermal shutdown
• Reference voltage: 0.8V
• Fixed frequency: 370kHz
• Soft start
• Compact package: MFP8 (200mil) with heat sink
