Description

The OPTIREG™ linear TLF4477-3LA is a monolithic integrated dual channel low drop out voltage regulator

capable of supplying loads up to 300 mA. For an input voltage up to 40 V the TLF4477-3LA provides an

adjustable output voltage in the range from 3 V up to 20 V in a thermally enhanced PG-TSON-14 package.

The channel specific current monitors of the TLF4477-3LA provide access to unique diagnostic and protection

features. They measures the output currents and translate them to a proportional voltage at the current sense

output CSOx. The output current limits for each channel can be manually set by via an external resistor.
