TLF42772EPXUMA1

TLF42772EPXUMA1 is an OPTIREG™ low dropout, linear voltage regulator. It is the ideal companion IC to supply critical applications requiring tight current limitations and diagnostics. It provides monitoring and protection features as well as a high-side power switch. It is a monolithic integrated low dropout voltage regulator that can supply loads up to 400mA. For an input voltage up to 40V, the TLF4277-2EP provides an adjustable output voltage from 3V to 16V. The integrated current monitor is a unique feature that provides diagnosis and system protection functionality. The TLF4277-2EP monitors fault conditions such as overtemperature and output overvoltage and indicates that at the current sense output. The maximum output current limit of the TLF4277-2EP is adjustable to provide additional protection to the connected load. Potential applications include automotive sensor supply, automotive telematics systems, camera and radar supply.
