TPS7B7701/02-Q1 Single/Dual Antenna LDO

Texas Instruments TPS7B7701/02-Q1 Single/Dual Antenna LDO is a low dropout regulator with current sensing designed to operate with a wide input-voltage range. This LDO provides power to the low-noise amplifiers of the active antenna through a coax cable with 300mA per channel current. Each channel also provides an adjustable output voltage from 1.5 to 20V. The Texas Instruments TPS7B7701/02-Q1 offers diagnostics through the current sense and error pins. A high-side current sense circuitry provides a proportional analog output to the sensed load current to monitor the load current. The accurate current sense allows detection of open, normal, and short-circuit conditions without further calibration. A current sense can be multiplexed between channels and devices to save ADC resources. Each channel also implements an adjustable current limit with an external resistor.
