Infineon TLF42772ELXUMA2

The TLF4277-2EL is the ideal companion IC to supply active antennas for car infotainment applications. The adjustable output voltage makes the TLF4277-2EL capable of supplying the majority of standard active antennas such as: • FM/AM • DAB • XM • SIRIUS The TLF4277-2EL 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 TLF4277-2EL 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. Via the enable function the IC can be disabled to lower the power consumption. The PG-SSOP14 EP package provides an enhanced thermal performance within a SO8 body size.

Symbol Views

(not all views will be available for every part)

Normal: Standard and most popular representation of schematic symbol

ALT_1 (IEEE view): Symbol representation in a way that is more graphical in explaining what the purpose of each pin is. For connectors and most discretes (as we use these views) it is simply an alternate view for people to use depending on the situation. For instance connectors can be generally an input, an output or neither. Resistors can be vertical or horizontal.

ALT_2 (demorgan): Demorgan is a name for an equivalent Gate structure. so for instance an AND gate and an OR gate can be represented by its Demorgan equivalent of a NOR gate.

Sometimes a device is fractured into multiple symbols (often for high pin count parts). If that is the case, you can preview the different symbols that make up the device by selecting them in this drop down.
