Infineon - TLF4277-2LD - A monolithic integrated low drop out voltage regulator

Infineon – TLF4277-2LD – A monolithic integrated low drop out voltage regulator

Active Antenna Supply IC in tiny TSON-10 package with current sense for antenna status monitoring and error detection. 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 and SIRIUS. TLF4277-2 has two package options. The SSOP-14 EP package provides an enhanced thermal performance within a SO-8 body size. The TSON-10 package is a 3.3 x 3.3 mm leadless package with excellent thermal performance and the capability for Automated Optical Inspection (AOI).
