L7987L

61 V 2 A asynchronous step-down switching regulator with adjustable current limitation

Input Voltage Min Volt4.5
Input Voltage Max Volt61.0
ECCN USEAR99
ECCN EUNEC
Packing TypeTube
RoHs compliantEcopack2
GradeIndustrial
Package NameHTSSOP16

The L7987L device is a step-down monolithic switching regulator able to deliver up to 2 A DC. The output voltage adjustability ranges from 0.8 V to almost VIN. The embedded switchover feature on the VBIAS pin maximizes the efficiency at light load. The adjustable current limitation, designed to...
