TPS7B7701QPWPRQ1 Automotive Single And Dual-Channel Antenna LDO With Current Sense

Product Description
TPS7B7701QPWPRQ1 devices feature a single and dual, high-voltage low-dropout regulator with current sensing, designed to operate with a wide input-voltage range from 4.5 V to 40 V (45-V load dump protection). These devices provide power to the low-noise amplifiers of the active antenna through a coax cable with 300 mA per channel current. Each channel also provides an adjustable output voltage from 1.5 V to 20 V.
