TLF4277-2LD

The TLF4277-2LD 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 TLF4277-2LD 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.
