Single-Chip Voltage Regulator Simplifies Car Antenna Design

The TLF 4277 single-chip linear voltage regulator comes with integrated diagnosis and car-radio-system protection functions. Designed for active antenna applications in automotive infotainment systems, the low-drop-out voltage regulator has adjustable output voltage to support the majority of standard active antennas, including FM/AM, DAB (Digital Audio Broadcast), and the XM and SIRIUS satellite radio bands. With its integrated current monitor and adjustable current limitation, the TLF 4277 can help reduce the number of discrete components for active antenna applications by approximately 50 percent. The AEC-Q100 qualified device is protected against failure situations, such as short-circuit of the output against ground or battery voltage, over-temperature, and over-current. Infineon’s TLF 4277 single-chip voltage regulator is available now in production volumes. The device is RoHS compliant and comes in a SSOP-14 EP (exposed pad) package providing enhanced thermal performance. Pricing starts at $1.11 each in 1000-unit quantities.
