Description

The TLF4277-2LD is the ideal companion IC to supply active antennas for car infotainment and telematics

applications. The adjustable current limitation, adjustable output voltage, and the diagnostic features make

the TLF4277-2LD capable of supplying the majority of standard active antennas, such as GPS, GNSS, FM/AM,

DAB, XM, and SIRIUS.

The TLF4277-2LD is a monolithic integrated low dropout voltage regulator capable of supplying loads up to

300 mA. For an input voltage up to 40 V, the TLF4277-2LD provides an adjustable output voltage in a range

from 5 V up to 12 V. The integrated current monitor function is a unique feature that provides diagnosis and

system-protection functionality. Fault conditions such as overtemperature and output overvoltage are
