Description
TLE42644G 5 V 100 mA Automotive LDO Regulator
The TLE42644G is an automotive low-dropout fixed regulator that converts inputs up to 45 V to a regulated 5 V output. It supports up to 100 mA, draws 40 µA typical quiescent current and includes current limiting and overtemperature shutdown.
What TLE42644G Is Designed to Do
The TLE42644G is an automotive low-dropout fixed regulator that converts inputs up to 45 V to a regulated 5 V output. It supports up to 100 mA, draws 40 µA typical quiescent current and includes current limiting and overtemperature shutdown. Final suitability depends on the complete circuit, software, thermal, mechanical, qualification and lifecycle requirements.
For sourcing, the base family name is not enough. The full TLE42644G ordering code, package, packing format, revision or grade, source condition and required inspection evidence should be confirmed against the actual order.
