The TLF4277-2EP is the ideal companion IC to supply critical applications requiring tight current limitation and diagnostics. It provides monitoring and protection features as well as a high side power switch. The TLF4277-2EP is a monolithic integrated low dropout voltage regulator that can supply loads up to 400 mA. The adjustable output voltage makes the TLF4277-2EP capable of supplying the majority of standard active antennas such as:
• FM/AM
• DAB
• XM
• SIRIUS For an input voltage up to 40 V the TLF4277-2EP provides an adjustable output voltage from 3 V to 16 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.
Via the enable function the IC can be disabled to lower the power consumption.
The PG-TSDSO-14 package provides an enhanced thermal performance within an SO8 body size.
