The TPS7B770x-Q1 family of devices feature a single and dual, high-voltage low-dropout regulator (LDO) with current sensing, designed to operate with a wide input-voltage range from 4.5V to 40V (45V load dump protection). These devices provide 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 1.5V to 20V.
These devices provide diagnostics through the current sense and error pins. To monitor the load current, a high-side current-sense circuitry provides a proportional analog output to the sensed load current. The accurate current sense allows detection of open, normal, and short-circuit conditions without the need for further calibration. Multiplex the current sense between channels and devices to save analog-to-digital converter (ADC) resources. Each channel also implements adjustable current limit with an external resistor.
An integrated reverse polarity diode eliminates the need for an external diode. These devices feature standard thermal shutdown, short-to-battery protection on the output, and reverse current protection. Each channel has internal inductive clamp protection on the output during inductive switch off.
These devices operate over a –40°C to +125°C ambient temperature range.
