TLF4277-2EL

Description:

The TLF4277-2 is the ideal companion IC to supply active antennas for car infotainment applications. The adjustable output voltage makes the TLF4277-2 capable of supplying the majority of standard active antennas such as:
• FM/AM
• DAB
• XM
• SIRIUS

The TLF4277-2 is a monolithic integrated low drop out voltage regulator capable of supplying loads up to 300 mA.
For an input voltage up to 40 V the TLF4277-2 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 monitored and indicated at the current sense output. The maximum output current limit of the device is adjustable to provide additional protection to the connected load.
